Add red preset

[shypard]

Hi,

this PR adds a red color scheme to the presets. This is especially helpful when doing visual astronomy observations at night. I also added the translations (using Deepl :D). Would you have a look at it?

Cool, approved, thanks!

Not sure if I'm gonna release it right away since there might be some extra unrelated stuff that I need to add.

But for sure your changes will go into the next release :+1:

Great, thanks! 😄
