DOC: use logo for SIG/addons

Thank @ewilderj :-)

Like it a lot, but IMO its a little too large? Can we re-size in HTML on github markdown?
e.g. <img src="logo.jpg" width="200" height="100"> or some size that makes sense?

[facaiy]

Totally agreed. How about the new one? Dose it look better?

So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored or co-authored by someone other than the pull request submitter. We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this state. It's up to you to confirm consent of all the commit author(s), set the cla label to yes (if enabled on your project), and then merge this pull request when appropriate.

ℹ️ Googlers: Go here for more info.

@facaiy I clipped some of the whitespace around the text and uploaded a local file so we don't need to worry about the link. If you like the image better, should we merge it into community or is the static file in repo okay?

[facaiy]

I prefer public url to static file in the repo, but both are fine. And I'm afraid svg format cannot play well with markdown, while png format perhaps is better for web :-)

[facaiy]

Sean, I'd like to leave it up to you :-)

[seanpmorgan]

So I think we'll meet somewhere in the middle. I do think SVG is preferred format for web, but to be fair that wasn't a true svg graphic, just an image imported into svg.

I'm uncomfortable with the URL link as it's outside of our control and could be broken without our knowledge. So PNG in repo I think is a good middle ground. I could live with the URL link, but I think it needs to be cropped anyway.
