bug: Q broke SSH

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

AL2 remote from macOS

### Expected behaviour

Running git operations should work as usual

### Actual behaviour

```
/home/hazout/.local/share/amazon-q/ssh_inner: line 15: Bad configuration option: setenv
/home/hazout/.local/share/amazon-q/ssh_inner: terminating, 1 bad configuration options
fatal: Could not read from remote repository.
```

### Steps to reproduce

Q is installed on a remote AL2 machine, while I am SSHing into it via macOS terminal.
Running any git related command shows this error. I'm not sure why it's trying to do anything related to Q.
