[FIX] theme_vehicle: fix btn-lg size

This commit removes the modified size for large (lg) buttons. They were
far too big. It also slightly changes the medium buttons accordingly.
This is not supposed to change anymore in stable versions but in this
case the big buttons were causing issues in eCommerce pages.
