Make TC39 meeting notes discoverable

[scottgonzalez]

@rwldrn posts meeting notes from TC39 meetings in https://github.com/rwldrn/tc39-notes. We should make it easy to discover these notes.

Can we reword this to say "Add a link to Rick's exhaustive and thankless meeting notes"?

[rdworth]

Thank you @rwldrn !

We might be able to just git submodule https://github.com/rwldrn/tc39-notes as a folder in here and it would pretty much just work yeah?

[scottgonzalez]

Not really, it's in a pretty different format, so we'd need to do some processing on it. I'm not really concerned with whether or not this content ends up on meetings.jquery.org, just that it's discoverable from there.

[rdworth]

We could just add a link to the sidebar then?

[scottgonzalez]

That works for me, though we should probably have a visual distinction (either a rule, another header, or some other indication) that this is different from the other meeting notes.

[rdworth]

Makes sense. Will also be easier from implementation side.
