Rollup merge of #81697 - xfix:every-doc-alias, r=Mark-Simulacrum

Browse source 
Add "every" as a doc alias for "all".

This matches [Array#every](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/every) in JavaScript.

Oddly enough, `core::iter::Iterator::all` appears twice. This appears to be a rustdoc bug which I decided to fill in as #81696.
