Fix Gitea SSH probe in plugin installer — drop bogus 'info' command

The probe ran 'ssh git@$ip info' expecting Gitea's banner in the response,
but 'info' is a Gitolite convention Gitea doesn't implement — it returns
'error: Too few arguments' instead, which never matched the grep, so a
real reachable Gitea host was never detected. Confirmed on HOST2: connecting
with no trailing command returns Gitea's actual banner correctly.
