[quick_actions] add localizedSubtitle for iOS (#8038)

Add the localizedSubtitle field on quick actions for iOS

flutter/flutter#129759

Pre-launch Checklist
 I read and followed the [relevant style guides](https://github.com/flutter/packages/blob/main/CONTRIBUTING.md#style) and ran the auto-formatter. (Unlike the flutter/flutter repo, the flutter/packages repo does use dart format.)
