Hey mbrat2005, thanks for creating this PR.

We noticed that this PR is ammending some things related to policies (definitions or assignments) 🔍

Thanks for this however, please keep in mind we replicate all policies from our upstream repo https://github.com/Azure/Enterprise-Scale (via some GitHub Actions) into these Bicep modules.

So it may be that this PR may be closed and we ask you to re-submit the changes to the respective code in our other repo.

However, we will review and advise further anyway but this is just a friendly premptive message and reminder of how policies are used and updated in this repo.

Thanks from your friendly msft-bot.
