Status change (approved) - follow up actions

🎉 as y'all might have heard - this project is now officially a [Jupyter Software Subproject](https://jupyter.org/governance/software_subprojects.html) 🎉

However, we need to complete a few tasks to align ourselves with the requirements set by Jupyter governance.

TODO:

- [ ] [Decision making](https://jupyter.org/governance/decision_making.html)
- [ ] Establish an internal council (and decision-making processes)
- [ ] Document the above in this repository
- [x] Nominate a single representative to the SSC (though I think this is covered already by @isabela-pf, let me know if I am wrong)
- [ ] Update this repo to take the form of our team compass (see resources below)
- [x] Align with the licensing guidelines and practices of the Project Jupyter https://github.com/jupyter/accessibility/pull/101
- [x] Follow Jupyter’s trademark, branding, and intellectual property guidelines. (done - we do not modify the logo, and the one we use is fair use)


🔗 Relevant resources:

- [JupyterHub team compass](https://jupyterhub-team-compass.readthedocs.io/en/latest/)
- [Governance docs on SSC representation)(https://jupyter.org/governance/software_subprojects.html#ssc-representation)
- [useRknowledge base - proposed governance](https://gitlab.com/rconf/userknowledgebase/-/issues/78) based on the [scikit-learn governance model](https://scikit-learn.org/stable/governance.html)

Start by reviewing the Jupyter decision-making guidance, the JupyterHub team compass, and the linked governance resources. Done means establishing an internal council and decision-making process, documenting them in this repository, and updating the repository to follow the team compass format.
