Amending the GitHub README to reflect mailing list status

[divya-mohan0209]

Summary

I was trying to sign up for the Chaoss DEI WG mailing list linked in the README. This doesn't seem to exist anymore on the LF lists.

Background

I was trying to sign up for the Chaoss DEI WG mailing list linked in the README. This doesn't seem to exist anymore on the LF lists. It could cause confusion for people looking to sign up. Additionally, I also noticed that on the KB page, the mailing list seems to have been struck off.

Details

Modifying the GitHub README to either reflect the strike off or removing the entry completely would be the best way forward. However, since I'm relatively new I am unsure of the exact specifics of what could be implemented.

Outcome

Better clarity for newcomers like myself, I guess?

Thanks for this issue @divya-mohan0209

Looking a bit more, @ElizabethN -- I'd suggest that we put the DEI README on this week's agenda. I think the entire thing could use a little attention.

I won't be able to attend the meeting, since it's at a very inconvenient hour for me. However, I can check the notes & work on revamping the DEI README if a consensus is reached.

No problem! We will talk about it there and then update this issue and respond in Slack as well.
