DOH not more accessible due to v2 packaging

[ewilly]

Describe the bug

Since v2 push, DOH is no more accessible : domain.tld/dns-query is rejected by ssowat (You've just been SSOed)

Context

• Hardware: not relevant
• YunoHost version: 11.2.8
• I have access to my server: yes
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• If upgrading, current package version: You've just been SSOed

Steps to reproduce

```
curl --doh-insecure --doh-url https://domain.tld/dns-query www.google.com
```

Expected behavior

Not being SSOed

Root cause

The content of /etc/ssowat/conf.json is wrong for api permission : cat conf.json | grep "dns-query" produce domain.tld/re:domain.tld/dns-query instead of re:domain.tld/dns-query. I temporary fix it by adding a persistent rule.
