Rollup merge of #152113 - Kobzol:fix-codebuild-summary, r=marcoieni

Fix GitHub CI summary in CodeBuild

We need to copy the summary only after the data is copied out from the Docker image in Docker-in-Docker/CodeBuild scenarios. This was broken for many months now.

Compare the summary https://github.com/rust-lang/rust/actions/runs/21663321354 (before) and https://github.com/rust-lang/rust/actions/runs/21671277310 (after) - the dist-x86_64-linux job now correctly contains the summary generated by `opt-dist`.
