chore: use actions-tagger to promote a major tag on every release

[juanitosvq]

According to the github actions versioning guide, actions publishers should have a major tag (v1, v2, etc) which points to the latest version of any minor/patch release of their action, for ease of use by the others.

This action doesn't currently do that, so I am leveraging the actions-tagger here, which will push a new major tag on every release.

Happy to get feedback!

@pascalgn any chance you can take a look at this? Thanks!
