Code Review
Thanks for adding documentation for the new tidb_restore_registry system table! The description is clear and helps users understand its purpose. I have one minor suggestion to make the description even more concise, in line with the style guide's emphasis on avoiding unnecessary words and repetition (Style Guide, Line 24).

- Documentation Conciseness: The description for
tidb_restore_registrycan be made slightly more concise while retaining its meaning. This aligns with the style guide's principle (Line 24) of avoiding unnecessary words for better readability.
Merge Readiness
This pull request adds important documentation for a new system table and is well-prepared. The suggested minor refinement for conciseness can be considered by the author. As a reviewer following the persona guidelines, I cannot approve pull requests. However, from a content perspective, these changes look good to merge after the author has reviewed the feedback and any other necessary approvals are obtained.

The current description is clear and accurate. For improved conciseness and to adhere to the style guide's principle of avoiding unnecessary words1, you might consider this slightly shorter phrasing:
