[Beta] Resolve diff discussions with Duo
## Release Notes Resolving code review comments used to mean switching to your editor, implementing the fix, committing, pushing, and then manually closing the thread — a slow, repetitive cycle that compounds across every unresolved discussion in a merge request. Now, you can click "Resolve with Duo" on any diff discussion, and GitLab Duo will read the review comment and its surrounding code, implement the change, commit it to your branch, and resolve the thread — all while leaving a reply explaining exactly what it did and why.
