Proposed implementation details (optional)

Like the cmdlet Get-AzRoleAssignment include a parameter -IncludeClassicAdministrators to be able to delete Classical Admin

Get-AzRoleAssignment -IncludeClassicAdministrators

Remove-AzRoleAssignment -SignInName $SignInName -RoleDefinitionName "ServiceAdministrator" -Scope $Scope -IncludeClassicAdministrators
