Rollup merge of #101624 - notriddle:notriddle/search, r=GuillaumeGomez

rustdoc: remove unused CSS `#search { position: relative }`

This was added in 611d0e6, to allow its child `#results` element to be absolutely positioned inside it. The child stopped being absolute in 8c04695.

To keep the layout looking the same, the links need to not have `width: 100%` any more, relying instead on the box naturally growing to fit because it has `display: block`.
