Subject: [PATCH] Rollup merge of #83678 -
 GuillaumeGomez:hack-Self-keyword-conflict, r=jyn514

Fix Self keyword doc URL conflict on case insensitive file systems (until definitely fixed on rustdoc)

This is just a hack to allow rustup to work on macOS and windows again to distribute std documentation (hopefully once https://github.com/rust-lang/rfcs/pull/3097 or an equivalent is merged).

Fixes https://github.com/rust-lang/rust/issues/80504. Prevents https://github.com/rust-lang/rust/issues/83154 and https://github.com/rust-lang/rustup/issues/2694 in future releases.
