Subject: [PATCH] Set `@typespec/compiler` as a `peerDependency` in library
 templates (#4685)

As specified in [the
documentation](https://typespec.io/docs/extending-typespec/basics#step-3-defining-dependencies):
> Use `peerDependencies` for all TypeSpec libraries (and the compiler)
that you use in your own library or emitter.
