Describe the bug

If the last commit in e.g. the main branch has skip ci in its commit message, creating a tag on top of that commit does not trigger the CI as it results in an empty pipeline.

Cant reproduce this behavior with Gitea as Gitea is using something like created tag v0.4.0 as pipeline.Message on tag event while on GitHub pipeline.Message is the commit message of the head commit for tag events.
