Describe the bug
Description of issue you're seeing...

The deployment of the sample repo shouldn't hit this error.

To Reproduce
Steps to reproduce the behavior...

I don't know if this happens every time but since I'm just supposed to be able to azd up - there shouldn't be any fix I have to do.

1. azd auth login
2. azd up
3. results
4. @pamelafox pointed me to the role.bicep file's code to generate the guid.

Deployment Error Details:
HashConflictOnDifferentRoleAssignmentIds: A hash conflict was encountered for the role Assignment ID. Please use a new Guid.

TraceID: bba916d63a752327c6e22415b019f3d1

Expected behavior
The core files need to generate unique GUIDs to get around this issue.

Environment
Information on your environment:
* Language name and version
* IDE and version : [e.g. Visual Studio 16.3] - Codespaces only

Additional context
Add any other context about the problem here.

My ideas:

1. We should probably add principalType to guid() as that could differ between roles that otherwise share same characteristics
2. That wasnt Dina's issue though, I don't believe, I think Dina just ran into a hash collision? So maybe we should add uniqueString to the end of the guid?
