Add tagging support

[ToMe25]

This pull request adds the ability to tag the new commit in the same action, by supplying it with a tag name.

If you don't think this matches what this action is meant to do feel free to close this pr.

Hey, thanks for the PR! I'll look into it as soon as I can ;)

Hey, I've added this in v4.2.0 (also available via the v4 and latest refs)
Just a note: if a tag already exists it will be updated, which is different from what you have originally coded: I hope this works out for you, but I guess the majority of people would prefer it like this, since workflows are made to run multiple times, and I see how tagging builds and so would be easier this way.
Thanks again for the PR :)

[ToMe25]

Yes, thats probably the better way.
I wont be able to use this action, as after i created this pr,
i figured out that what i wanted conflicts with the intention(and implementation) of this action.
I have found another way to do it, and hope this addition will help other people :)
