In #13374 we updated the commented-out `license_path` in the packaged example
configuration file to match the existing documentation. Although this config
value was commented-out, it was reported that changing the value was
confusing. Update the commented-out line to the previous value and update the
documented examples to match that. This matches most of the examples for
Consul/Vault licensing as well. I've double-checked the tutorials and it looks
like it'd been left on the previous value there, so no additional work to be
done.
