Summary of changes:

Updated docs/gdevelop5/extensions/share-extension.md to document the new ability to set custom icons for individual behaviors and custom objects within an extension (PR #8472). Added a note explaining that once the extension itself has an icon, each behavior and custom object can be given its own distinct SVG icon via the Icon URL field in their configuration panel.

No other commits required documentation updates — the remaining changes were internal bug fixes, runtime refactors, and UI polish with no new user-facing concepts.

Please review the changes carefully before merging.
