fix(ConnectionIdOverwrites): connection id overwrites in eval

[akshaylive]

In eval context studio_client.get_resource_overwrites() is invoked. This client provides overrides for connections as ConnectionId instead of connectionId. Allowing parsing of both fields using AliasChoice, but we prioritize connectionId over ConnectionId for backwards compatibility. Serialization will always be done to connectionId.
