    devel-docs: bump official macOS support to 10.12 on stable 2.10…
    
    … series as well (it was already so in the `master` branch).
    
    See discussion:
    https://gitlab.gnome.org/GNOME/gimp/-/issues/7515#note_1318891
    
    Basically it's probably possible to backport some changes and still
    support an older version, but we clearly lack contributors on macOS so
    the current unique one's decision matters most.
