Rollup merge of #92947 - vacuus:rustdoc-core-visit-path, r=camelid
rustdoc: Use `intersperse` in a `visit_path` function (~~Is there a better way to word the title?~~ Eh, this works, I guess.) I'm surprised that the compiler didn't complain when I left out the `.to_string()`, but hey, if it works then it works.
