Problem

Every once in a while get folks asking if they can put the Matplotlib logo on a tutorial or something and I keep forgetting what the answer is.

Suggested Improvement

It'd be useful to have that officially documented, preferably with PNG & SVG versions of the short & long logos.

Pandas has a good example of this sort of page, which they add onto their citation page
https://pandas.pydata.org/about/citing.html

Extra Info

Like the pandas page, we have the HTML color values of the logo care of @dorafc
