Output timestamp

Output tag timestamp the same way https://github.com/WyriHaximus/github-action-get-previous-tag does.

As a side note, tags usually don't even have a timestamp. The commit does or the GitHub release does.

That's true, later I was thinking about the missunderstood.

No issues, I've found a workaround, just by using the RegExp and "brute force" doing the merge and pushing it it's enough, I don't need to check the timestamp in advance because if the merge was already done in the past, the git push is mostly a no-op, so besides wasting more CPU time, there's no major issue.
