Configure GitHub Action

[namoscato]

Thanks for this script!

I found this useful to do some simple YAML front matter linting and ended up wrapping it in a GitHub Action which looks something like this to use:

uses: namoscato/splinter@v1
with:
  rules_file: .splinter
  src_paths: src

This also registers a custom problem matcher which creates GitHub check run annotations, i.e.

If this is something you are open to merging and/or adding to the marketplace, I am happy to help out with some more documentation.
