Conduct TW review of recent Gitaly and Gitaly Cluster doc page changes
Issue
To address a time-sensitive issue, the MR !71329 (merged) was merged without having completed a Technical Writing review. While our process would have Technical Writing not be a blocker (hence the approval and merge), we should go back and review the changes based on our style and tone guidelines.
The deliverable for this issue is one or more linked MRs that provide a TW review for the changes to the affected doc pages.
