Description

jj git clone git@github.com:martinvonz/jj.git fails if the user is using an SSH key with a
hardware security key such as the types described in Github's SSH key documentation.

Steps to Reproduce the Problem

1. Create a new SSH key with ssh-keygen -t ecdsa-sk -C "your_email@example.com" and a hardware security key.
2. Run jj git clone git@github.com:martinvonz/jj.git.
3. See an error and the repo is not cloned.

Expected Behavior

The repo should be cloned.

Actual Behavior

jj git clone git@github.com:martinvonz/jj.git
Error: authentication required but no callback set; class=Ssh (23); code=Auth (-16)
Hint: Jujutsu uses libssh2, which doesn't respect ~/.ssh/config. Does `ssh -F /dev/null` to the host work?
