Add support for GitHub Issues

Add support for GitHub Issues, sponsored by @launchgood and @matmar10.

The action will now work out of the box for any condition that is relevant for Issues (match on title, authors, body) is now available. Activating only requires adding the issues trigger to the existing workflow configuration as explained in the README installation section. The configuration remains backwards compatible and only requires a new field if you plan to use Issues for scheduled workflows.

Thanks again to @launchgood and @matmar10 for sponsoring the feature. If your org finds labeler useful please consider joining them as sponsors!
