[Feature]: Update-AzCommunicationService doesnt allow to link a domain

### Description of the new feature

The Update-AzCommunicationService has no parameter to link the communicationservice to a domain.
It's only possible to do it through the API by adding properties.linkedDomains in the body request. Is that possible to add a -linkedDomains parameter for the Update-AzCommunicationService cmdlet

### Proposed implementation details (optional)

_No response_

Start with the Update-AzCommunicationService cmdlet and compare its parameters with the linked Azure Communication Services REST update API. Trace how the request body is built, then verify that a -LinkedDomains value is accepted and sent as properties.linkedDomains.
