Tags Github Pull Requests with affected Lerna packages

This action labels your pull requests based on modified files within the pull request. It takes the package name and adds an optional prefix to it before setting it as a label. Other labels should not be touched by this action.

This action should be run on 'pull_request_target' events BUT consider to not checkout the target commit. For information about this read here. Additionally this prevents malicious actors to spam your repository with new tags!

This action is used for example by donmahallem/js-libs

This config show cases a simple workflow to label pull requests with already known packages.
