BicepNet - Restore Modules broken

[coolhome]

Describe the bug
Trying to use the bicep public registry in a bicep template produces an error during Build-Bicep

This is working using the latest bicep cli to restore.

Build-BicepNetFile: main.bicep(9,34) : Error BCP192: Unable to restore the module with reference "br:mcr.microsoft.com/bicep/avm/res/resources/resource-group:0.2.1":

Thanks for the bug report! I suspect this might be connected to #318, since the underlying repository has some differences. We'll have a look as soon as possible!
