Design: Add Fedora i3 SIG Meeting thumbnail for YouTube videos
I created this thumbnail image for use with YouTube videos since I
already had a template. I am sharing the source file and rendered PNG
version for quick use by other members on the team. We can also use it
on any docs page too, if we ever have a reason for that…
