Vincent Eberle requested to merge fix_docu into NIFTy_8 Jan 02, 2023

Fixes issue #356 (closed)

sphinx removed logo variables from 5.3 to 6. These lines fix the CI and produce the same page as before.

html_theme_options = {
    "logo": {
        "image_light": "nifty_logo_black.png",
        "image_dark": "nifty_logo_black.png"
    },

The rest is cosmetics.
