Pull request overview

This PR adds a new -ResiliencyView parameter to the Get-AzVmssVM cmdlet to enable monitoring of the Resilient Delete feature for Virtual Machine Scale Set (VMSS) VMs. The parameter retrieves the ResilientVMDeletionStatus property, which indicates whether automatic delete retries are in progress, failed, or not started. This implementation aligns with the design proposal referenced in issue #1527.

Key changes:

• Added -ResiliencyView switch parameter to retrieve resilient VM deletion status
• Updated help documentation with new parameter description and usage example
• Added test coverage for the new functionality
• Fixed a spelling error in help documentation ("Species" → "Specifies")
