Build/Test Tools: Introduce a workflow for checking built files.
There are several files generated and updated by the build process that are under version control. Including changes to these files is a common missed step for contributors regardless of experience level.
This introduces a workflow that checks for changes to versioned files as a result of other changes in pull requests and commits them back to the head branch. Because this workflow requires the pull_request_target event instead of pull_request, local references to reusable workflows should never be used.
In addition to improving the contributor experience, this also opens the door to use Dependabot for monitoring npm dependencies, many of which produce changes to built files when updating.
