Reduce size of logo while increasing font size

From 5633 to 3210 bytes while reducing borders around the text.

How:
- import MicroPythonOS-logo-black-long.svg into Gimp, rasterized at 266x59 at 130 dpi
- crop it to 240x35 px, making sure to have at least 0.5 pixel border around the content to make sure no half-transparent pixels are cut off
- export as PNG with maximal compression and all options (like save resolution, save background color) unchecked
