Community: Supporters, contributors, sponsors, and users

[dylans]

One set of questions people have when they choose any new technology include who supports it, who are the contributors/leaders, who sponsors the project, and who are well known users.

Currently supporters/sponsors would include SitePen, users would include Daimler, Esri, and others (we can ask on Discord for people who want to get listed), and contributors could be a list of people who have submitted PRs, and perhaps a team directory at some point.
