rustdoc: rename syntax highlighting CSS class `attribute` to `attr`

Link classes use the abbreviation `attr` ...

https://github.com/rust-lang/rust/blob/2afca78a0b03db144c5d8b9f8868feebfe096309/src/librustdoc/html/static/css/rustdoc.css#L255-L259

... so why does syntax highlighting use the full word?
