When filtering out the user-surfaced 'voiced in announcement channels' permission when creating/editing roles, I didn't consider that we should always display this option because subchannels can be announcement threads. Now that they can be, I'm not going to filter this option out anymore. This will mean that ticking this checkbox, users with this role will be able to talk in all announcement channels (including the community root if it's an announcement thread).
This shouldn't require a migration since all it does is display the option in the permissions list client-side to be able to be toggled.
