ref(replay): Send SDK version in Replay events

[Lms24]

Since we now export Replay via the Browser SDK we can now send the SDK version instead of the Replay package.json version, allowing us to get rid of the custom rollup config to inject said version.

closes #6366

Just to be sure, version will already have been replaced somewhere else here, right?

[Lms24]

Yes, version is set automatically during SDK initialization:

sentry-javascript/packages/react/src/sdk.ts

Lines 9 to 16 in 6557844

	options._metadata.sdk = options._metadata.sdk || {
	name: 'sentry.javascript.react',
	packages: [
	{
	name: 'npm:@sentry/react',
	version: SDK_VERSION,
	},
	],

The reason for providing the fallback here is that users can potentially delete it or use a custom or an old client that doesn't yet have getSdkMetadata.
