IdentitySet.cs does not contain a Phone property

[rslavey]

Describe the bug

When I call the /v1.0/communications/callRecords/{id}, the participants object can contain a "user" or a "phone". However, the SDK does not recognize this.

"participants": [ { "spoolApplicationInstance": null, "applicationInstance": null, "acsApplicationInstance": null, "application": null, "phone": null, "acsUser": null, "spoolUser": null, "user": { "displayName": "xxx", "tenantId": "xxx", "id": "xxx" }, "device": null, "encrypted": null, "guest": null, "onPremises": null }, { "spoolApplicationInstance": null, "acsApplicationInstance": null, "applicationInstance": null, "user": null, "application": null, "phone": { "displayName": null, "tenantId": null, "id": "xxx" }, "acsUser": null, "spoolUser": null, "device": null, "encrypted": null, "guest": null, "onPremises": null } ]

Error in Visual Studio: 'IdentitySet' does not contain a definition for 'Phone' and no accessible extension method 'Phone' accepting a first argument of type 'IdentitySet' could be found (are you missing a using directive or an assembly reference?)

This exists in the Identity property of ParticipantsV2 and OrganizerV2, but these are not returned by the call to CallRecords today.

Expected behavior

A call record should return a CallRecord object with a valid Participant phone, e.g.,

var id= record.Participants?.Select(x => x.User ?? x.Phone)

How to reproduce

Make Graph API call to CallRecord:

    _graphClient
    .Communications
    .CallRecords[id]
    .GetAsync();```

Attempt to return participant phone property:

`var id= record.Participants?.Select(x => x.User ?? x.Phone)`

### Other information

The Microsoft.Graph.Models.IdentitySet class should contain a Phone property that mimics the User property.
