Clarify the remote font config setting a bit

Some people test Nextcloud and Collabora Online without setting up SSL.
For security reasons, Collabora Online production builds refuse to load
remote configuration via http://. It is possible to use http:// only
with debug builds, that users build for themselves. The feature simply
does not work, when someone tries http:// with a production build,
only logs will tell "Remote config url should only use HTTPS protocol"
