Update Gitlab agent version outdated text
What does this MR do and why?
When the GitLab agent is out of sync with the KAS, we show a warning and an explanatory tooltip. The wording there might be confusing as it mentions the GitLab version while it looks for the KAS version.
This MR also cleans up the gitlabVersion usage as it was left there with Compare agent version against KAS version (!87010 - merged) to ensure backward compatibility. We don't need it anymore.
