If a version has already been tagged, it causes the workflow to fail

[Nitemaeric]

I'm likely missing something, but I've been trying to setup the following logic in GitHub Actions with this action:

On pushes to main, when there is no git tag equal to {gem_name}::VERSION, run the rubygems/release-gem action.

Right now, if I run the action on pushes to main, it will fail if the tag already exists.

Any suggestions?
