Report GitLab version in SiteSpeed test results
Print GitLab version in SiteSpeed performance results table similar to the GPT. Additionally, we can explore adding in a repo link to the exact GitLab commit the test environment is running on as a convenience so users can see the commits details and find out if their changes are in, e.g. https://gitlab.com/gitlab-org/gitlab/-/commits/ba818874cc3 (similar to performance#427)
