feat(devcontainer): Add SSH feature in devcontainer.json

[maaz7409]

Currently, we can't connect to codespace with configuration as per .devcontainer/* as it lacks ssh feature in devcontainer.json.

Adding this enables ssh connection.

Confidence Score: 4/5

The change is non-blocking, but the devcontainer lock file should be regenerated to preserve reproducible feature resolution.
