rustdoc: remove CSS @media (min-width: 701px)

The two rules within it can and should be done without the separate
media query:

  * There ain't no rule saying a viewport can't be `700.5px` wide, since
    hardware pixels can be finer than CSS pixels.

  * The rule for the first example-wrap child should probably apply
    on mobile.

  * The rule for the source sidebar is overriden by the mobile rule
    setting `max-width: 100vw`, so it can be merged with the rest
    of the styles.
