feat(docs): document image bubble menu form and unlink

[joaopcm]

Summary

Documents the new image bubble menu surface shipped in #3371:

• BubbleMenu.ImageDefault props: wider excludeItems ('edit-link' | 'unlink') and new validateUrl / onLinkApply / onLinkRemove
• Image compound components: BubbleMenu.ImageUnlink and BubbleMenu.ImageForm
• Image bubble menu CSS hooks: data-item="unlink" selector plus form / input / apply / unlink

Depends on #3371 — merge that first so the docs match shipped code.

Test plan

• Run the docs locally and verify the BubbleMenu API reference page renders the new props and compound rows
• Verify the Styling page shows the expanded image bubble menu CSS block
