rustdoc: remove no-op CSS h3.variant, .sub-variant h4 { border-bottom: none }

notriddle · notriddle · commit 19b297c6e1f9 · 2022-09-30T00:00:54.000-07:00
This rule, added in 69df43b to override the default `h4` style, has been obsoleted when a65c98f changed it so that only the top docblock put `border-bottom` on `h4.`
