Add non-developers contribution section and an owner for it

[castrojo]

This adds a skeleton section to the contributor guide for a non-developer section. I've put it in it's own document with a link from the guide so that the team can iterate quickly on one file.

@kbarnard10 is already an org member so I've added her as a reviewer to the guide since she is working on this.

Generally lgtm, but what happened to the idea of changing the name from non-Dev to non-Code as that's more explicit on what we’re trying to accomplish?

The doc doesn't mention a slack channel. Can we also mention the contribex slack channel here? For a new contributor, it's easier to get involved by starting to talk to somebody on slack rather than waiting for a meeting. :)

@cblecker any reason why can't we unhold this?
