Summary

Made two concise documentation updates to reflect user-facing engine changes:

1. docs/gdevelop5/all-features/resources-loading/index.md — noted that Preload object, Unload object and Object preloaded now accept an optional Object scene parameter, allowing loading objects from another scene before it's displayed (#8592).
2. docs/gdevelop5/behaviors/events-based-behaviors/index.md — added the new Layer property type (stored as text) to the list of property types available on custom behaviors (#8596).

The "Select All" Events Sheet shortcut and the custom-object camera fix were not documented, since CLAUDE.md guidance says not to explain standard shortcuts and the camera change is a behind-the-scenes fix making existing camera actions work inside custom objects.

Please review the changes carefully before merging.
