Rollup merge of #92602 - jsha:source-link-2, r=GuillaumeGomez

Make source links look cleaner

Change from syntaxy-looking [src] to the plain word "source".

Change the syntaxy-looking `[-]` at the top of the page to say "collapse".

Reduce opacity of rightside content.

Part of #59851

r? `@GuillaumeGomez`

Demo: https://rustdoc.crud.net/jsha/source-link-2/std/string/struct.String.html

[Discussed on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/display.20of.20source.20link).
