Graph Bicep module does not work with deployment stack

Bicep version
Bicep CLI version 0.44.1 (28275db947)

Resource and API version
Which Microsoft.Graph resource and API version has the issue?

• br:mcr.microsoft.com/bicep/extensions/microsoftgraph/v1.0:1.0.0
• Microsoft.Graph/servicePrincipals@v1.0

Auth flow
CD deployment in Azure Devops pipelines using the AzureCLI@2 task and a managed identity with the required Application.Read.All and AppRoleAssignment.ReadWrite.All permissions.

Deployment details
Please refer to #302

Describe the bug
When deploying the bicep mentioned in #302 using deployment stack, the error (also described in #302) is triggered.

To Reproduce

1. Create a bicep deployment that deploys the bicep in #302.
2. Have a managed identity that has the Application.Read.All and AppRoleAssignment.ReadWrite.All Graph permissions.
3. Use that managed identity (e.g. in a CD pipeline in Azure DevOps) and run az stack sub create to deploy it.

Additional context
It is quite a showstopper since it doesn't work with deployment stacks...

Start with the deployment details in issue #302 and reproduce the reported failure using the Graph servicePrincipals@v1.0 resource and az stack sub create with the stated managed identity permissions. Done means the Bicep deployment completes successfully through a deployment stack without triggering the error described in #302.
