feat(draft_notes): add PublishAllDraftNotesWithOptions

What does this MR do?

Adds PublishAllDraftNotesWithOptions to the draft notes service. The bulk publish endpoint (POST /projects/:id/merge_requests/:iid/draft_notes/bulk_publish) accepts note, internal, and reviewer_state fields to attach a summary comment and set the review state when publishing all pending draft notes, but the current PublishAllDraftNotes cannot pass a body.

• Adds PublishAllDraftNotesOptions (note, internal, reviewer_state).
• Adds a PublishAllDraftNotesWithOptions sibling method following the existing CancelJobWithOptions/GetJobArtifactsWithOptions precedent, deprecated on arrival with a note that the options merge into PublishAllDraftNotes in 4.0.
• PublishAllDraftNotes keeps its exact signature and now delegates with nil options (same shipped pattern as CancelJob); its wire shape is pinned by a test.
• Also corrects the doc link on PublishAllDraftNotes, which pointed at the single-note publish anchor.

Why

Needed by gitlab-org/cli!3909 glab mr note publish command, which publishes a pending review with an optional summary note and reviewer state.

Review notes

• The nil-opt delegation sends a literal null JSON body where the old method sent no body — byte-identical to the shipped CancelJob → CancelJobWithOptions delegation, and pinned by TestPublishAllDraftNotes.
