Add button glyphs support to selection hint on language screen

The language screen has a "Press Space, Z, or V to select" hint, which
I forgot to update for supporting button glyphs in #943, so this commit
does.

    <action_hint>Press Space, Z, or V to select</action_hint>
    <gamepad_hint>Press {button} to select</gamepad_hint>
