rollup merge of #20092: barosl/rustdoc-line-number-clickable

Browse source 
While talking on IRC, someone wanted to post a link to the Rust source code, but while the lines of the rendered source code do have anchors (`<span id="[line number]">`), there is no convenient way to make links as they are not clickable. This PR makes them clickable.

Also, a minor fix of the FAQ is included.
