Change image based on white-/darkmode

[Mondei1]

GitHub actually supports conditional images based on prefers-color-scheme.

See https://github.com/GiorgosXou/Random-stuff/tree/main/Programming/StackOverflow/Answers/70200610_11465149 for example or their Stackoverflow answer: https://stackoverflow.com/questions/65413712/changing-readme-md-image-display-conditional-to-github-light-mode-dark-mode

But here is a quick copy-paste from their answer:

  <source media="(prefers-color-scheme: dark)" srcset="https://raw.githubusercontent.com/GiorgosXou/Random-stuff/main/Programming/StackOverflow/Answers/70200610_11465149/w.png">
  <source media="(prefers-color-scheme: light)" srcset="https://raw.githubusercontent.com/GiorgosXou/Random-stuff/main/Programming/StackOverflow/Answers/70200610_11465149/b.png">
  <img alt="Shows a black logo in light color mode and a white one in dark color mode." src="https://user-images.githubusercontent.com/25423296/163456779-a8556205-d0a5-45e2-ac17-42d089e3c3f8.png">

I think this is very useful to include, as some logos look terrible with the wrong background color.
