Rollup merge of #86956 - cuviper:unalias-every, r=m-ou-se

Revert "Add "every" as a doc alias for "all"."

This reverts commit 3545036 (#81697) for "every" and closes #86554 in kind for "some".

The new [doc alias policy](https://std-dev-guide.rust-lang.org/documentation/doc-alias-policy.html) is that we don't want language-specific aliases like these JavaScript names, and we especially don't want to conflict with real names. While "every" is okay in the latter regard, its natural pair "some" makes a doc-search collision with `Option::Some`.
