[coc-tf] Announcing updated CoC

Dear TF members,

We're ready to publish the updated draft+labs article. However, the RIPE 
Chair has suggested it would be good to take the summer period into 
account and have the webinar/deadline for comments in September.

Regarding the timeline, how about the following:

- Very soon (today/tomorrow) publish labs article/updated draft
- Webinar: 3 September (~13:00 UTC)
- Deadline for comments: 17 September

If this timeline works, then it might be better to hold off on 
publishing the registration form for the webinar until August. It seems 
a bit odd asking people to register 2 months in advance, and some might 
forget by then. Instead, we could note that we're planning a webinar for 
early September in the labs article/announcement and share the details 
closer to then.

Let me know what you think.

PS: I'll ask Karla to handle these last bits, as I'm currently on 
vacation for the next ten days - she's subscribed to this list.

Cheers

Ant
