Github Action that gets the latest tag from git

This action has only one output, namely, tag for the latest tag this action finds. When no tag is found or another error occurs it exits with code 1.

The following example works together with the WyriHaximus/github-action-next-semvers and WyriHaximus/github-action-create-milestone actions. Where it provides the previous tag from that action so it can supply a set of versions for the next action, which creates a new milestone. (This snippet has been taken from the automatic code generation of wyrihaximus/fake-php-version.)
