Describe the bug
tl;dr You can't install both certbot-dns-google-domains 0.1.11 and certbot-dns-duckdns 0.9 at the same time.

You can't use both GoogleDomainsDNS and DuckDNS at the same time. I originally set up certificates using duckdns, but then wanted to set up a personal personal domain so I purchased a domain using Google domains. Unfortunately you can't use both at the same time. certbot-dns-duckdns depends on zope.interface 5.4 and certbot-dns-google-domains depends on zope.interface 6.0 and they're incompatible. The error from pip looks like this:

Error: pip's dependency resolver does not currently take into account all the packages that are installed. This behavior is the source of the following dependency conflicts.
certbot-dns-duckdns 0.9 requires zope.interface~=5.4.0, but you have zope-interface 6.0 which is incompatible.

Nginx Proxy Manager Version
2.10.3

To Reproduce
Steps to reproduce the behavior:

1. Go to SSL Certificates
2. Click on Add
3. Add a ssl certificate for DuckDNS
4. Afterward, try to add another certificate for GoogleDomainsDNS

Expected behavior
You should be able to add SSL certificates for both domain providers
