Introduce governance documentation and co-maintainers

[tordans]

Recently, we added co-maintainers to the id-tagging-schema repo and used a GOVERNANCE.md doc to describe roles, people and processed.

This change was merged on 2024-08-07.

During the iD Community Meeting on the same day we discussed the extend this setup to iD and the schema builder repo as well.

Today I had a chat with @tyrasd during which we create the doc in this PR that adapts the document from the id-tagging-schema repo for this Project.

The plan we discussed during the community meetup is to have this PR open until after SOTM Kenya to collect feedback.

The main goal of this change is, to introduce co-maintainers (@k-yle and myself) and describe the roles and processes that are used to maintain iD as a community project.

Thanks for this document. I fully support the addition of the two of you as co-maintainers and like that you'd have the ability to merge/close clear-cut PRs yourselves while being involved in the bigger ones.

One small note - I currently have the Triage role on this repo. I could either be added to the document under that section, or removed from having Triage permissions. I'd be happy to continue helping (modestly) with that, especially knowing the project will have additional maintainer bandwidth with three of you. I can submit a commit to this PR if there's interest in me keeping those permissions (or if you'd like to discuss once it's finalized that the three of you are all maintainers).

Sorry @nickrsan for this oversight and thanks for reaching out. I just added you to the doc.
We simply forgot to go into details on this section when we copied it over from the id-tagging-schema.

Did we miss anyone else who is still active with the triage role?
I don't have access to the permission list. But maybe waiting for feedback here is a good way to see who is still active. :-)
