[feature] Rolling release versions

Many github actions have a tag to mark the patch version (v1.1) and a tag to mark a backwards compatible release (v1). It would be nice to add this feature to this plugin to move the v1 tag on release.

Then you could also reuse this action to release your own action.

No file or test is named. Start by reading the action's existing version-bumping and tagging flow, then determine how releases are handled. Done means a release moves the backwards-compatible v1 tag, supports the v1.1 patch tag, and allows the action to release another action.
