rustdoc: remove unused CSS `.docblock a:not(.srclink)`

This selector was added in c7312fb, because the list of impl items could be nested below `docblock`.

https://github.com/rust-lang/rust/blob/c7312fbae4979c6d4fdfbd1f55a71cd47d82a480/src/librustdoc/html/render.rs#L3841-L3845

Now that rustdoc toggles have been switched to `<details>`, there shouldn't be any need to put things inside docblock containers just to give them disclosure toggles.
