CI/test-python: give launch-kit-backend CHAIN_ID, not NETWORK_ID (#2327)

* CI/test-python: give LK ID of chain, not network

For CircleCI job test-python, change docker config for
launch-kit-backend to set an environment variable for the chain ID,
not for the network ID.  This was failing on all branches after a recent
update to the `0xorg/launch-kit-backend:v3` tag.

* Update docker config used for local testing

* Update documentation of test environment
