fix: update docs-sync instructions (#2336)

Update the `docs-sync.yml` workflow to encourage Claude to be more
focused during docs creation.

Currently Claude will make many small changes to documentation files,
many of which are redundant, complicating code review. This PR
encourages Claude to be more focused and succinct, simplifying review
and making docs more maintainable.
