No support for ecdsa-sk ssh keys

Similar to #416 , can't use it on Windows 11 Pro 24H2 Build 26100.3915 Resource Package 1000.26100.83.0 with native OpenSSH Agent running on named pipe \\.pipe\openssh-ssh-agent.
It does works to use native OpenSSH Client, but JS ssh2 seems to be the problem. Would there be a way to use the system ssh client for making the connection instead, either directly, or as a proxy?
