What is in this Pull Request ?

This PR adds support for sensitivity labels while creating modern sites.

As mentioned in the below URL, it is dependent on core library where it has been merged.
pnp/PnP-Sites-Core#2668

A thing to note here, in case of modern communication sites, the labels appear instantly whereas in case of team sites, it takes couple of hours before they appear. If user wants to validate the label, they can go to the Azure portal and check the label value.

I tested it and it doesn't work for me yet as it will use Microsoft Graph to create the site which does not yet support adding a sensitivity label. I have updated a PR I'm having open with PnP Sites Core making similar modifications to force the SharePoint API to be used whenever a sensitivitylabel has been provided: pnp/PnP-Sites-Core#2672

We'll need to wait for that to be merged before we can finalize testing this PR.

Another issue I have found is that if you're using a Graph Token, is that the GetGroupCreationContext does not succeed in retrieving the existing sensitivity labels on the tenant and thereby fails to assign the label to the site. When authenticating directly to SharePoint using i.e. -WebLogin, it does work fine. Don't see a solution for that issue, so leaving that as is.
