Poetry hangs resolving ssh dependencies from unknown hosts

Description

Running poetry lock will hang forever without any indication of why.

Running poetry lock -vvv shows ssh's interactive prompt, e.g.

The authenticity of host 'github.com (140.82.116.4)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

This prompt can be accepted and future runs can succeed.

Workarounds

Run poetry lock -vvv and interact with the ssh prompt

Poetry Runtime Logs

issue does not occur with `-vvv`

Start by reproducing dependency resolution with poetry lock against an SSH dependency whose host is unknown, then compare it with poetry lock -vvv and the recorded SSH prompt. Trace the lock command's handling of the interactive prompt and define done as avoiding an indefinite hang while presenting a clear diagnostic or noninteractive outcome.
