OpenJS Foundation Finish Line

This is an annotated version of the checklist at https://github.com/openjs-foundation/project-onboarding/issues/36, specific to Electron's current state. Once completed, I will respond in that issue with the completed checklist which will then (hopefully!) be passed to the CPC for approval. If completed, I can't foresee any non-trivial roadblocks.

- [x] Adopt the OpenJS Foundation Code of Conduct
- [x] https://github.com/electron/electron/pull/23137
- [x] ~Update project CoC reporting methods to include OpenJS Foundation escalation path~ doesn't need to be done :)
- [x] ~note from @bnb: There does not seem to currently be clear and documented guidance on what this is, how to implement it, or what it fully entails from the OpenJS Foundation CPC. There is work being done to improve this, but that work is not completed. One specific point - the ability for CoC rulings to be escalated above and outside of Electron's Community and Safety structure to the CoCP group within the OpenJS Foundation for an "appeal" - is something that Electron would likely want to have feedback on.~
- [x] openjs-foundation/cross-project-council#439
- [ ] @groundwater owning working on the Foundation with this.
- [x] Identify and document other core project infrastructure
- [x] document by @codebytere: https://hackmd.io/@codebytere/rk2-IRPaL
- [x] Add or Update Governance.md document (required for Impact stage)
