Remove internal developer configuration from CONFIG_ENV_VARS

[joe4dev]

Motivation

Using LAMBDA_DEV_PORT_EXPOSE within Docker breaks Lambda leading to a connection error because the LocalStack container cannot reach the Lambda container:

Failed invocation MyHTTPConnectionPool(host='127.0.0.1', port=58301): Max retries exceeded with url: /invoke (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0xffff40fa18a0>: Failed to establish a new connection: [Errno 111] Connection refused'))
