Create "v1" tag for automatically following this action's updates without modifying workflows

[rhysd]

I'd like to suggest to create a v1 tag for making users automatically follow v1.x.y updates without modifying their workflows like other actions in actions organization doing (e.g. actions/checkout@v4).

I know that Dependabot can automatically maintain the versions of actions used in workflow. But they require PR reviews and some people (including me) would not want to spare time for them.
