Pixel Eagle logo is missing from `about` page

[rparrett]

It seems that the image may have gone away in the v2 rollout.

I noticed a couple other things:

• The svg logo is quite large, several hundred kilobytes gzipped
• The pixel eagle logo on the about page might need some help with alignment.
  It looks a bit off compared to GitHub Actions to the left. .feature-icon { height: 50px; } helped.

Guessing there might be other changes to be made to this page, so I just opened an issue.

added back the tiny png, thanks!

and yeah, forgot I made the svg quickly and way too big, I need to simplify it...
