favorite folders followup (#8570)

Something changed, which affected the Favorite folder picker checkbox
styles -- fixed it!
Cleaned up code in `CurrentWorkspaceMemberFavoritesFolders` - removed
redundant filtering since favorites are already filtered in
`usePrefetchedFavoritesData`.
Regarding issue #8569 - I am not sure what to do in this case. Since
Folders data is gated by a feature flag, we can't use it in
`CurrentWorkspaceMemberFavoritesFolders` to ensure the favorite section
renders with empty folders. Currently, the section only appears when at
least one favorite exists - may be leave this section open at all times
or fix this bug after removal of the feature flag?
