mediawiki.ui: Remove remainder `text-shadow`

The `text-shadow` property on primary buttons was probably introduced
for a fake 3D effect and also because the colors were lighter in
order to set the white text apart. None of this is true with our
WikimediaUI color palette any more so let's remove this remainder.
