rustdoc: make settings radio and checks thicker, less contrast

This is very dependent on subjectivity and what screen you use,
but this change makes the radio buttons' outer circle less ugly.

This is because I could see the pixels very clearly, thanks to the
very thin line and high contrast. This change makes both less
severe, giving your browser's antialiasing algorithm more to
work with. Since it's thicker, lowering the contrast shouldn't
impact visibility.
