rustdoc: merge separate `.item-info` CSS

Rough timeline:

* The longer `.content .item-info` selector originated in
  110e7270ab7b0700ce714b8b1c7e509195dea2c4. No reason seems to be given in
  the PR why it needed the `.content` part, but it was probably added because
  of <https://github.com/rust-lang/rust/blob/110e7270ab7b0700ce714b8b1c7e509195dea2c4/src/librustdoc/html/static/rustdoc.css#L476-L478>.
  That selector with the margin-bottom was removed when CSS containment
  was added in 8846c0853d8687fda0e5f23f6687b03b243980ee.
* `.stability` was renamed `.item-info` in
  caf6c5790a858893c1d32ed2054c9577d12e7493.
* The selector without the `.content` was added in
  d48a39a5e24ab08f727d1c919dc2af98c333ad14.
