`sq keyserver --help` should show what the default keyserver is

0 dkg@alice:~$ sq keyserver --help
sq-keyserver 
Interacts with keyservers

USAGE:
    sq keyserver [OPTIONS] <SUBCOMMAND>

OPTIONS:
    -h, --help                       Print help information
    -p, --policy <NETWORK-POLICY>    Sets the network policy to use [default: encrypted] [possible values: offline, anonymized, encrypted, insecure]
    -s, --server <URI>               Sets the keyserver to use

SUBCOMMANDS:
    get     Retrieves a key
    help    Print this message or the help of the given subcommand(s)
    send    Sends a key
0 dkg@alice:~$ 

However, it works just fine if i don't specify -s or --server, so it has some built-in default. I suspect it's keys.openpgp.org. It would be good if the help text were to show what the default is.
