[ISSUE]: GitLab CI tag pipelines result in an incorrect version

GitVersion package

GitVersion.Tool

GitVersion version

6.0.2

Operating system

Linux

What are you seeing?

When running a tag pipeline, the tag is incorrectly detected as a branch. GitVersion gets its branch name from the environment variable CI_COMMIT_REF_NAME, but this variable is set to the tag when it's running a tag pipeline.

Example:

• Tag a commit as v1.1.2
• This executes a tag pipeline in GitLab CI
• The resulting SemVer will be 1.1.3-v1-1-2.1

What is expected?

A SemVer of 1.1.2 (in this example)

Steps to Reproduce

See example in the issue description. More details in the discussion #4183

The two issues are basically the same, yes. But this issue is about the incorrect usage of a GitLab CI specific environment variable, the other issue is about Azure Pipelines.

It might be better if there's a universal fix, as you said. But I believe this is a quick fix and it mirrors the fix for GitHub Actions which seems to have had a very similar problem, so it might still be a good idea to apply it for now.
