Add support for group_membership_filter in azuread

[bigkevmcd]

Issue: rancher/rancher#46209

Problem

It's not currently possible to configure the user-group filter from Terraform.

Solution

This adds support for configuring the group_memembership_filter for Azure which configures a filter for querying groups for a user.

Manual Testing

Configured a simple "azuread" resource...

resource "rancher2_auth_config_azuread" "azuread" {
 // other fields omitted for simplicity
  group_membership_filter = "startswith(displayName,'admin')"
}

And confirmed that these are configured on the azuread AuthConfig resource, and that they are updated when changed.

Automated Testing

Tests were added for the new behaviour.
