Update Dockerode, for small bugfixes & ssh2 (inconsequential) vuln fix

The SSH vulnerability (CVE-2023-48795) is very interesting and worth
avoiding in general, but in our case AFAIK it's not possible to use HTTP
Toolkit with a Docker engine over SSH (the only cases where this module
is used) and so the relevant code is never actually run.
