Rollup merge of #91102 - jsha:theme-anchor, r=GuillaumeGomez

Set color for <a> in a more straightforward way.

Previously, we set the default color for <a> tags to black, and then had an override with a bunch of not() clauses to set anchors in
docblocks to blue.

Instead, we should set the default color for <a> to blue (or equivalent in other themes), and override it for places like the sidebar or search results, where we don't want them to be styled as links.

Demo at https://rustdoc.crud.net/jsha/theme-anchor/std/string/struct.String.html. This should result in no visible changes.
