Not able to get "q doctor" to work in EC2.

### 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

Linux 6.12.35-55.103.amzn2023.x86_64 - Amazon Linux 2023.8.20250721

### Expected behaviour

I added the following two lines to /etc/ssh/sshd_config in the EC2:
AcceptEnv Q_SET_PARENT
AllowStreamLocalForwarding yes
In spite of this "q doctor" does not work.

### Actual behaviour

The following message is returned when I run "q doctor":

✘ sshd config: Could not read sshd_config

The /etc/ssh/sshd_config file needs to have the following line:
AcceptEnv Q_SET_PARENT
AllowStreamLocalForwarding yes

If your sshd_config is already configured correctly then:
1. Restart sshd, if using systemd: sudo systemctl restart sshd
2. Disconnect from the remote host
3. Run q integrations install ssh on the local machine
4. Reconnect to the remote host and run q doctor again

See https://docs.aws.amazon.com/amazonq/latest/qdeveloper-ug/command-line-autocomplete-ssh.html for more info

✘ Doctor found errors. Please fix them and try again.

If you are not sure how to fix it, please open an issue with q issue to let us know!
