Auto merge of #32100 - SimonSapin:patch-6, r=alexcrichton
"can be built on Ref::map"… how? Now that `std::cell::Ref::filter_map` and `RefMut::filter_map` are deprecated, using them gives a warning like: ``` script/dom/element.rs:754:9: 754:24 warning: use of deprecated item: can be built on Ref::map, #[warn(deprecated)] on by default ``` But it’s not at all obvious *how* the functionality can be built on `Ref::map`. This PR adds to the warning message a crates.io URL for a crate that does.
