Rollup merge of #124630 - Kobzol:yaml-anchor, r=pietroalbini

CI: remove `env-x86_64-apple-tests` YAML anchor

This PR removes the only remaining anchor in the definition of CI jobs. This anchor made it annoying to copy-paste the job e.g. to PR CI.

Fixes: https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/How.20do.20you.20edit.20PR.20CI.20to.20test.20PR.20now.3F
