Logo updates
We need the following updates to the logo:
- The T-Shirt logos (black and white) are clipped at the right edge, so the S in OS is not completely round, this needs to be fixed
- The "logo" and "logo_small" logos are not the latest version of the logo and should be updated
- We need a dark mode (white on transparent) and a light mode (black on transparent) logo
- We need a non-transparent black-on-white logo
- There is a black and a white logo in the book that should be tracked in this repo
