docs(coc): Turn the code of conduct email into a form that a group of people will get

In #887, we noticed the code of conduct has an email that is likely not part of our team. I suggest that we consider using a google form that goes to a general email (google group maybe?) that a few of us get. I don't anticipate us getting lots of emails but if we have a form, then we can easily monitor a private google group and add more people to it in the future if we need to.

This might be another pr - but i wonder who owns this email? is this really the one we should be using in this repo?
