🐛 Bug Report

What is the problem?

This line appears to add a region to the arn of the service linked role. This causes AccessDenied errors on iam:PassRole when it is deployed because IAM is a non-regional resource.

Reproduction Steps

1. install modules via npm install
2. compile code via npm run build
3. run synth via cdk synth
