Use fake-seam-connect module to run the tests (#67)

* Use fake-seam-connect module to run the tests

* Start fake server for every test fn separately

* Fix lint

* Setup node during test workflow

* Use npm registry for fake-seam-connect

* Use context manager to fix lint

* Run the fake-seam-connect server entrypoint directly without an additional script

* Remove start-fake-seam-server.js

* Don't pipe subprocess's output and error + minor corrections

* Update fake server start script name, pin fake-seam-connect version

* Rename find_free_port to get_port

* ci: Generate code

* Update command that starts fake server in conftest.py
