Include user's preferred timeZone as property in the user resource

Currently you can get a user's default https://docs.microsoft.com/en-us/graph/api/resources/mailboxsettings?view=graph-rest-1.0#:~:text=the%20user%27s%20mailbox.-,timeZone,-string in the user's https://docs.microsoft.com/en-us/graph/api/resources/mailboxsettings?view=graph-rest-1.0. This requires at least MailboxSettings.Read scope. We would like to be able to get the user's preferred timezone back as a property in the https://docs.microsoft.com/en-us/graph/api/resources/user?view=graph-rest-1.0#properties resource, which could use a User.Read scope.

rational: In the current world of hybrid work, a users timeZone is an integral part of a users information, and as such should not require an additional web request and an additional scope to get that info.
