SPOTenantSettings: Missing support for property TenantDefaultTimezone

[salbeck-sit]

Description of the issue

The resource returns information that is available through Get-PnPTenant. The corresponding Graph-cmdlet Get-MgAdminSharepointSetting returns quite a number of the same properties and additionally TenantDefaultTimezone. The latter would be very nice to set first thing in order to not having to do it from every SPO-site being created.
I'm not sure if any other resources mix permissions/cmdlets like this - ie calling New-M365DSCConnection twice with different workloads - but I'd think that this would be the easy way. The PNP-module could be used to provide validation for the timezone via 'Get-PnpWeb -Includes RegionalSettings.TimeZones' (see https://www.sharepointdiary.com/2017/06/sharepoint-online-change-time-zone-using-powershell.html) - but another option is to just let the Update-cmdlet throw an error (and log it).

Are all current properties part of the MSGraph cmdLet? Changing to the graph cmdLet would also allow for a better permission management in regards to access rights for SPO. https://learn.microsoft.com/en-us/graph/api/sharepointsettings-update?view=graph-rest-1.0&tabs=http

Unfortunately not. There is some overlap but nowhere near enough for a direct replacement
