feat: publish new GitHub Enterprise Cloud (GHEC) specific @octokit/openapi-types-ghec package, plus lots of API changes

* feat: publish new `@octokit/openapi-types-ghec` package with types for APIs supported by GitHub Enterprise Cloud, including GitHub Enterprise Cloud-exclusive APIs not available to other customers on `api.github.com`
* feat: remove types for GitHub Enterprise Cloud (GHEC) specific APIs from the `@octokit/openapi-types` package

BREAKING CHANGE: Types for API operations only available to GitHub Enterprise Cloud (GHEC) customers will no longer appear in the `@octokit/openapi-types` package. These will only appear in the GHEC-specific `@octokit/openapi-types-ghec` package. The `@octokit/openapi-types` package now only includes APIs available to customers on GitHub.com using the Free, Pro and Teams plans.
