Rollup merge of #55760 - jonhoo:no-intermediate-fonts, r=GuillaumeGomez

Remove intermediate font specs

This is a (much) more constrained version of #54772 that also aims at improving the situation in #34681. It removes any font specifications that are not the "official" rustdoc font, and instead relies on the browser to provide the fallback font if the official on is not available. On Linux systems, this is particularly important, as fonts like Helvetica, Arial, and Times often look pretty bad since they're pulled from extracted MS fonts. A specification like `serif` or `sans-serif` lets the browser instead choose a good font.
