Fix Recent Documents List (continues #8952) (#9919)

@SomeoneToIgnore This code should 100% work for future Zed users, but
for current Zed users, Zed's internal list of recents may not be synced
w/ macOS' Recent Documents at first. If needed this can be fixed by
calling `cx.refresh_recent_documents` on startup, but that feels a bit
unnecessary.

Release Notes:

- Fixes behavior of Recent Documents list on macOS
