fix(apple): select only entries named Assets.car as asset catalogs (#4094)

inspect-asset-catalog selected every bundle entry whose relative path
ended in Assets.car, so an unrelated NotAssets.car directory was listed
as a skipped catalog and, with no real catalog present, failed the
inspection instead of returning the empty inventory; a regular file such
as OldAssets.car would have been sent to assetutil. The selector now
compares the final path component exactly.

Fixes #3914
