Action Regex Match

This is a GitHub Action to do regex matching and output the matched text and groups captured by the given regex.

GitHub Actions natively supports some helpful functions, like contains and startsWith, but doesn't regex matching. This actions provides the missing, useful function.

It would be more useful to use this with other GitHub Actions' outputs.
