docs: note namespace apply/delete behaviors, fix metric (#17527)
This changeset includes some fixes to documentation discovered while working on
node pools, but we didn't want to include in the node pool PRs so they can get
backported easily:

* namespace apply/delete commands are forwarded to the authoritative region
* deleting a namespace requires there are no non-terminal jobs in any of the
  federated regions
* fixed a typo in the name of the `nomad.client.allocated.disk` metric

Usage: nomad namespace delete [options] <namespace>
Delete is used to remove a namespace.
If ACLs are enabled, this command requires a management ACL token.
You cannot delete a namespace that has non-terminal jobs. In federated
clusters, you cannot delete a namespace that has non-terminal jobs in any of
the federated regions.
