URL checker action is not cooperating with Rmds anymore

[cansavvy]

Even though I've tried going back to earlier versions of https://github.com/urlstechie/urlchecker-action/tree/0.2.3, it still is not cooperating with scanning Rmds anymore. It always tells me "no URLs detected"

I think this is because https://github.com/urlstechie/urlchecker-action/blob/master/entrypoint.sh hasn't frozen what version they use and updates to the python urlchecker pacakge that is underneath the hood: https://quay.io/repository/urlstechie/urlchecker/manifest/sha256:65edb42c5fda47c6b8668cee59b59d1eeb9e2b432711cdd3415bc569cfcfd635

SO, I think we should just switch strategies, and maybe use the package they use directly instead of using their action.

The fix for this is pushed, I'm just testing it out on various repositories before I send out the next release.

It's working! The only thing left is to provide a way for url's to be ignored, but I think this can be a later priority. Going to make a new issue for this.
