  software/rapid-cdn: avoid RegExp to validate hostnames

Using RegExp to validate hostnames is a bad practice, and has a lot of reasons to be wrong.
On top of that, the JSON Schema specification allows, since draft 7, to validate hostnames
against an IDN hostname, by using the `idn-hostname` format.

With these changes, IDN are now supported (.рф and .中國 for instance), and long TLD
should not be a problem anymore.

* master:
  software/erp5/upgrade_test: use 1.0.167.10 for old software
  software/nextcloud/test: adjust test
  software/jstestnode: use default firefox version
  software/cloudooo/test: snapshot test an odg to png conversion

With backported fixes so that old software supports debian 12

In 9636d79c (Nextcloud Upgrade fixes, 2023-12-13) parameter changed:
 - instance.trusted-domain-* parameters are replaced by instance.trusted-domain-list
 - the frontend is part of trusted domain, so with "bypassed" frontends
from slapos proxy the backend appears twice (because the backend URL is
returned as frontend URL)
