Unrolled build for rust-lang#135441
Rollup merge of rust-lang#135441 - compiler-errors:redundant-captures-lint, r=lqd Make sure to mark `IMPL_TRAIT_REDUNDANT_CAPTURES` as `Allow` in edition 2024 I never got sign-off on rust-lang#127672 for this lint being warn by default in edition 2024, so let's turn downgrade this lint to allow for now. Should be backported so it ships with the edition. ```@rustbot``` label: +beta-nominated
