Update our references and contact details on the Open edX Code of Conduct

[e0d]

Just noticed that our code of conduct reference older email address and may need some day 2 language changes.

https://open.edx.org/code-of-conduct/

This ticket is inclusive of discovery, proposal and implementation. A light review only should be necessary as we hopefully won't be changing anything substantive in the document.

Without seeing this ticket, I already updated a few weeks ago. I:

• Removed Nimisha
• Kept Ned
• Kept Sarina & Ed, but changed our email addresses

@e0d I did a review pass and the only things I can see that may need changing:

The Mission

Currently says, edX and the Open edX community seek to foster an open and welcoming environment to as wide a range of participants as possible. This mission takes priority over the letter of the rules.

Should I remove edX?

Contact email

Should I s/oscm@edx.org/ oscm@tcril.org/ - or are we using a different list?

:+1: Let's spot change those references and consider a larger rework later. I think most of the content is still correct.
