[ChristopherGLewis]

Description of the new feature

The Azure Rest API for subscrption -> List location has extended information for availabilityZoneMappings that has will shortly be enabled in Bicep.

Please add this to the current get-AzLocation (and possibly the equivalent Az CLI command)

Proposed implementation details (optional)

Either add this information as an additional object in the return or add a parameter to enable output
