v1 tag isn't updated as newer tags are released - easy solution available

[consideRatio]

Thanks for providing this action!

I've come to expect that github actions providing a v1 tag or branch will update it as new v1.x.y releases are made. In this repo, the v1 tag isn't updated though. It is a chore to provide such updates manually, but there is a very quick and easy to deploy automation for this available. As a maintainer of a few GitHub actions, I've been very happy with this strategy so far.

All that is required is the addition of a workflow like this, using the Actions-R-Us/actions-tagger action.

For reference - v1 vs v1.4.1 tags
