Support overriding default organization settings

Created by: mbarbero

Currently, the script update org permissions based on https://github.com/EclipseFdn/eclipsefdn-github-sync/blob/fddcb4820699ee786a213f9a7aae7935346c516c/src/Sync.js#L63

Those default values are sensible for most org, but there are exceptions where we would want to not use those defaults.

We will need to be able to override those defaults (e.g., for temurin-compliance) either via additional metadata in PMI or directly in the script configuration.
