[Feature]: Managing PowerShell Modules in Runtime Environments and Retrieving Detailed Runbook Information

### Description of the new feature

How can I retrieve all the PowerShell modules containing  within the new feature called 'Runtime Environments'  (https://learn.microsoft.com/en-us/azure/automation/runtime-environment-overview)? Additionally, how can I retrieve information about which Runbook is assigned to which environment using only PowerShell?

Thank you

### Proposed implementation details (optional)

_No response_

Start with the linked Runtime Environments overview and review the existing Azure Automation PowerShell commands for module and runbook management. Done should provide a supported PowerShell way to list modules in runtime environments and identify which runbook is assigned to each environment.
