Prevent `<>` links to be interpreted for intra-doc links

As discussed in [this thread](rust-lang#96135 (comment)). As mentioned, the intra-doc RFC states that `<>` links shouldn't be potential intra-doc links:  https://rust-lang.github.io/rfcs/1946-intra-rustdoc-links.html#no-autolinks-style.

I renamed `markdown_links` into `potential_intra_doc_markdown_links` to make it more obvious what it's doing.
