Add support for Microsoft.Graph.Core >= 3.0.0 to Microsoft.Graph.Communications.Core

Describe the issue
Currently, Microsoft.Graph.Communications.Core is dependent on Microsoft.Graph.Core (>= 2.0.13 && < 3.0.0). Microsoft.Graph 5.x.x requires Microsoft.Graph.Core >= 3.x.x.

The impact of this is that by introducing calling functionality in my bot, my options are to either use Microsoft.Graph.Communications.Calls and back-port all other Graph calls in my project from the 5.x.x format back to 4.x.x, or manually handle the calling requests - neither of which are particularly inviting options.

Code Snippet

Expected behavior
Able to use Microsoft.Graph.Communications.Core (and subsequently Microsoft.Graph.Communications.Calls) with the latest Microsoft.Graph package.

Graph SDK (please complete the following information):
Microsoft Graph 5.16.0

Additional context
Apologies if this isn't the correct place to post this, I couldn't find anywhere more appropriate.

Start by reviewing how Microsoft.Graph.Communications.Core declares its Microsoft.Graph.Core version range and how Microsoft.Graph.Communications.Calls consumes it. Validate the dependency relationship against Microsoft Graph 5.16.0; done when both communications packages work with Microsoft.Graph.Core 3.x.
