Fix top_level_group_map comment

[m-bull]

The Kayobe monitoring group, not the contollers group, is mapped to the Kolla-Ansible monitoring group by default.

Code Review

This pull request provides a documentation fix within a commented-out example in etc/kayobe/kolla.yml. The change corrects the default group mapping for monitoring services from controllers to monitoring under kolla_overcloud_inventory_top_level_group_map. This aligns the example with the intended default behavior, improving configuration clarity for users. The change is correct and I have no further feedback.

Should we change the comment to just link to the defaults instead?

The network group is no longer the controllers too, and there's now a compute-vgpu group we don't mention at all

I guess we'd have to remember to update the link each release, but a grep -r <previous-release> should catch it - we have to do that in a few places, so seems like a reasonable tradeoff to me.

We've got NOTE(upgrade): which we use for stuff like that, as a thing to search for and update each release
