* Remove code that was hiding Go as a language option for k8s overlay resources. Mark input args type for Functions as optional in Go.
* Show a special note in the Go function's snippet when the function name does not match other languages.
* Make sure the draft PR stays assigned to the original author. Add some more comments.
* Remove logic to use the Go ModuleToPackage map to then lookup the relevant C# namespace. Make getLanguageModuleName a method of modContext since passing in a package is not needed anymore.
* Generate language package details in the index pages.
* Add a new DocLanguageHelper interface method to get to a module per-language.
* Add a new workflow file for automatically creating draft docs PRs for previewing resource docs for AWS and Kubernetes as a result of changes in the resource docs generator.
