chore(aws-eks): pin aws-cdk-lib devDependency to 2.47.0 (#22667)

The v2 release build is currently failing due to a cycle between `aws-cdk-lib -> @aws-cdk/aws-eks -> aws-cdk-lib`. This only occurs during the release build (and not the PR build) because we run `align-versions.sh` in the release build. I tested this locally and the error went away after pinning the version.
