Description

Hiya, I have a physical FIDO key that I use to authenticate SSH connections, for example when pulling/pushing to git remotes.
When I have enabled the new setting git.subprocess from #4979 I don't get any warning messages from the git subprocess?
The warning message I was expecting to see, but is now missing, is "Confirm user presence for key ..." as shown below.

Steps to Reproduce the Problem

1. jj config set --user git.subprocess=true
2. jj git fetch
3. FIDO key lights up and waits for user interaction.

Expected Behavior

# jj git fetch
Confirm user presence for key ECDSA-SK SHA256:xxx
User presence confirmed
Nothing changed.

Actual Behavior

# jj git fetch
Nothing changed.
