chore: ensure make gen runs on CI when docs are updated (#15252)

https://github.com/coder/coder/pull/15203 was merged with a failing
`make gen`, as it only updated the docs. This makes it so this can't
happen again.

The capitalization of the Go type used in the auto-generated docs
(`codersdk.OAuth2GithubConfig`) wasn't updated as it would technically
be a breaking change for the sdk.
