feat(nextjs): Add excludeServerRoutes option to manual setup page (#5789)

This adds the new `excludeServerRoutes` option in the nextjs SDK (added in getsentry/sentry-javascript#6207) to the docs. It also pulls all of the auto-instrumentation config into its own section in the manual setup page.

(Note: The only part of this which is actually new content is the `Opt Out of Auto-instrumentation on Specific Routes` section. Everything else is just stuff moving around.)

-_(New in version 7.14.0)_

-The SDK will automatically instrument API routes and server-side [Next.js data fetching methods](https://nextjs.org/docs/basic-features/data-fetching/overview) with error and performance monitoring To disable it, set the `autoInstrumentServerFunctions` to `false`.

-const moduleExports = {
-  sentry: {
-    autoInstrumentServerFunctions: false,
-  },
-};

-
-Under the hood, when using this option, the SDK is using a Webpack loader to wrap all your API route handlers and data fetching methods.
-
-If the automatic instrumentation doesn't work for your use case, API routes can also be wrapped manually using the `withSentry` function:
-
-```javascript {filename:pages/api/*}
-import { withSentry } from "@sentry/nextjs";
-
-const handler = (req, res) => {
-  res.status(200).json({ name: "John Doe" });
-};
-
-export default withSentry(handler);
-```
-
-```typescript {filename:pages/api/*}
-import type { NextApiRequest, NextApiResponse } from "next"
-import { withSentry } from "@sentry/nextjs";
-
-const handler = (req: NextApiRequest, res: NextApiResponse) => {
-  res.status(200).json({ name: "John Doe" });
-};
-
-export default withSentry(handler);
-```
-
-Data fetching methods can also be manually wrapped using the following functions:
-
-- `withSentryServerSideGetInitialProps` for `getInitialProps`
-- `withSentryGetServerSideProps` for `getServerSideProps`
-- `withSentryGetStaticProps` for `getStaticProps`
-- `withSentryServerSideErrorGetInitialProps` for `getInitialProps` in [custom Error pages](https://nextjs.org/docs/advanced-features/custom-error-page)
-- `withSentryServerSideAppGetInitialProps` for `getInitialProps` in [custom `App` components](https://nextjs.org/docs/advanced-features/custom-app)

+## Configure Server-side Auto-instrumentation
+
+The SDK will automatically instrument API routes and server-side [Next.js data fetching methods](https://nextjs.org/docs/basic-features/data-fetching/overview) with error and performance monitoring.
+
+### Disable API Route and Data Fetching Auto-instrumentation Entirely
+
+_(New in version 7.14.0)_
+
+To disable the automatic instrumentation of API route handlers and server-side data fetching functions, set the `autoInstrumentServerFunctions` to `false`.
+
+```javascript {filename:next.config.js}
+const moduleExports = {
+  sentry: {
+    autoInstrumentServerFunctions: false,
+  },
+};
+```
+
+With this option, under the hood, the SDK is using a Webpack loader to wrap all your API route handlers and data fetching methods.
+
+### Opt In to Auto-instrumentation on Specific Routes
+
+_(New in version 7.14.0)_
+
+If the automatic instrumentation doesn't work for your use case, you can turn it off globally and choose to only wrap specific API route handlers or data fetching functions instead.
+
+For API routes, use the `withSentry` function:
+
+```javascript {filename:pages/api/*}
+import { withSentry } from "@sentry/nextjs";
+
+const handler = (req, res) => {
+  res.status(200).json({ name: "John Doe" });
+};
+
+export default withSentry(handler);
+```
+
+```typescript {filename:pages/api/*}
+import type { NextApiRequest, NextApiResponse } from "next"
+import { withSentry } from "@sentry/nextjs";
+
+const handler = (req: NextApiRequest, res: NextApiResponse) => {
+  res.status(200).json({ name: "John Doe" });
+};
+
+export default withSentry(handler);
+```
+
+For data fetching methods, use the following functions:
+
+- `withSentryServerSideGetInitialProps` for `getInitialProps`
+- `withSentryGetServerSideProps` for `getServerSideProps`
+- `withSentryGetStaticProps` for `getStaticProps`
+- `withSentryServerSideErrorGetInitialProps` for `getInitialProps` in [custom Error pages](https://nextjs.org/docs/advanced-features/custom-error-page)
+- `withSentryServerSideAppGetInitialProps` for `getInitialProps` in [custom `App` components](https://nextjs.org/docs/advanced-features/custom-app)
+- `withSentryServerSideDocumentGetInitialProps` for `getInitialProps` in [custom `Document` components](https://nextjs.org/docs/advanced-features/custom-document)
+
+### Opt Out of Auto-instrumentation on Specific Routes
+
+_(New in version 7.20.0)_
+
+If you want auto-instrumenatation to apply by default, but want to exclude certain routes, use the `excludeServerRoutes` option in the `sentry` object in your `next.config.js`:
+
+```javascript {filename:next.config.js}
+const moduleExports = {
+  sentry: {
+    excludeServerRoutes: [
+      "/some/excluded/route",
+      "/excluded/route/with/[parameter]",
+      /^\/route\/beginning\/with\/some\/prefix/,
+      /\/routeContainingASpecificPathSegment\/?/,
+    ],
+  },
+};
+```
+
+Excluded routes can be specified either as regexes or strings. When using a string, make sure that it matches the route exactly, and has a leading slash but no trailing one.
