ssm-ssh does not work on Windows 10

[devbyaccident]

When attempting to connect to an SSM managed instance with ssm-ssh command on Windows 10 using latest OpenSSH build, this error is received from ssm-ssh

SSM inventory entity not recognised: {'Id': '<Instance ID>', 'Data': {}}
CreateProcessW failed error:2
posix_spawnp: No such file or directory

Possible fix is per microsoft/vscode-remote-release#18 (comment), this should be resolved by running ssh.exe on Windows instead of ssh.
