[FEATURE] Remove-PnPAzureADGroupMember should be able to remove Groups

[DBLHB]

Is your feature request related to a problem? Please describe.
Remove-PnPAzureADGroupMember currently only offers the possibility to remove members by UPN. It is not possible to remove a Group from a Group (aka nested Groups), because Groups don't have a UPN.

Describe the solution you'd like
Add a new parameter for removing objects (Users, Groups) by ObjectId
