Rustdoc style cleanups

 - Make "since" version numbers grey again (regressed in #92602).
 - Remove unneeded selectors for when crate filter dropdown is a
   sibling of search-input.
 - Crate filter dropdown doesn't need to be 100% width on mobile.
 - Only build crate filter dropdown when there is more than one crate.
 - Remove unused addCrateDropdown.
