CodeCov: Unhandled error occurerd when creating PR

### Describe the bug

An unhandled error `Unable to get ACTIONS_ID_TOKEN_REQUEST_URL env variable` occurs when creating a pull request.
It seems that the solution in [#34169](https://github.com/aws/aws-cdk/pull/34169) does not work...?

This error appears to happen on every PR.
Is there a way to fix it?

Example: https://github.com/aws/aws-cdk/actions/runs/14630503794/job/41051726081?pr=34198

```shell
Run actions/github-script@v7
Error: Error message: Unable to get ACTIONS_ID_TOKEN_REQUEST_URL env variable
