Rollup merge of rust-lang#106273 - notriddle:notriddle/source-content-overflow, r=GuillaumeGomez

rustdoc: remove redundant CSS `.source .content { overflow: visible }`

When added in 7669f04 / rust-lang#16066, the page itself was set to scroll. Now it's set so that the `example-wrap` is scrolling inside the page, so the overflow setting for the content is irrelevant.
