mac-capture: Undeprecate traditional capture sources on macOS 12

SCK has too many bugs on macOS 12 that don't like they will get fixed or
backported for it to be the recommended capture source.
This commit removes the "Deprecated" flag from traditional capture
source if the user is on macOS 12 (even if SCK is available) and marks
SCK as Beta.
