Rollup merge of rust-lang#91534 - jsha:heading-color, r=GuillaumeGomez

Make rustdoc headings black, and markdown blue Demo: https://rustdoc.crud.net/jsha/heading-color/std/string/index.html#structs https://rustdoc.crud.net/jsha/heading-color/std/string/struct.String.html#examples Fixes rust-lang#91304 r? ```@camelid``` /cc ```@GuillaumeGomez``` (Note: we may want to make rustdoc headings and markdown headings the same color -- rust-lang#90245 -- but we would want to do that intentionally; this is fixing up a change that did so accidentally)
