rspamd.com does not offer an IPv6

[keyhelp]

The website https://rspamd.com/downloads.html describes, how to install the latest rspamd version and that one should not use the outdated version from the default Debian/Ubuntu repositories.

If you are going to install rspamd on a IPv6-only system, you will face issues, because rspam.com does not offer an IPv6 address.

Adding - as described - the repository http://rspamd.com/apt-stable/ on an IPv6-only system has no effect and the installation of the latest rspamd version will not work - therefor it will fall back to the outdated rspamd version found in the default Debian/Ubuntu repositories.

IPv6 only systems can still use IPv4, there are more than one way to do so. I don't see any issues in that. Please also notice the following:

❯ host -t AAAA github.com                                                                                                                                                             
github.com has no AAAA record

Do you see such a disclaimer on github.com??

Anyway, I agree that we should mention that on the downloads instructions.
