- While doing some sanity checks over OpenSSH's code for how they handle
certificates authentication. I stumbled on an condition that checks the
certificate type is really an user certificate on the server-side
authentication. This checks seems to be a formality and just for the
sake of good domain seperation, because an user and host certificate
don't differ in their generation, verification or flags that can be
included.
- Add this check to the builtin SSH server to stay close to the
unwritten SSH specification.
- This is an breaking change for setups where the builtin SSH server is
being used and for some reason host certificates were being used for
authentication.

## ⚠️ BREAKING ⚠️
Like OpenSSH, the built-in SSH server will now only accept SSH user
certificates, not server certificates.
