"""Custom rollup_bundle for language service.
Overrides format to AMD and produces only umd and min, no FESM.
We do this so that we bundle all of the dependencies into the bundle
except for typescript, fs and path.
This allows editors and other tools to easily use the language service bundle
without having to provide all of the angular specific peer dependencies.
