Work with software projects to adopt new project governance

[mindthegab]

In #45 we've introduced a synthetic and simplified governance that fits in a CONTRIBUTING.md file.

Now that with #51 the governance was adopted we need to consider raising pull requests to projects to adopt this governance in their projects.

We'll outline progress here:

• [ ] Identify projects to submit PRs to
• [ ] Work with key projects to make sure they are prioritized
