Auto merge of #7463 - ThibsG:find_any_7392, r=xFrednet

Fix `any()` not taking reference in `search_is_some` lint

`find` gives reference to the item, but `any` does not, so suggestion is broken in some specific cases.

Fixes: #7392

changelog: [`search_is_some`] Fix suggestion for `any()` not taking item by reference
