Rollup merge of rust-lang#102125 - notriddle:notriddle/content-item-info, r=GuillaumeGomez

rustdoc: remove no-op CSS `.content .item-info { position: relative }`

This rule was added to help position the marker line in 110e727, which was a `position: absolute` pseudo-element that relied on its parent to put it in the right spot. (it was changed from a line to an arrow in 1ffb9cf, then a different arrow in ae3a53f).

The arrow was removed in 73d0f7c, so the `relative` position is no longer necessary.
