Rollup merge of #88699 - Mark-Simulacrum:fixes-cherry-picker, r=pietroalbini

Remove extra unshallow from cherry-pick checker

This is already done by https://github.com/rust-lang/rust/blob/13db8440bbbe42870bc828d4ec3e965b38670277/src/ci/init_repo.sh#L32-L36 on the beta channel, and git throws an error if you attempt to unshallow an already non-shallow repository.
