Override bootstrap's `scroll-behavior: smooth` to improve UX?

[lagru]

This is a usability suggestion and might be somewhat subjective. Especially for larger pages in scikit-image's API documentation, I've perceived the navigation with the right sidebar TOC as annoyingly slow. When I click an anchor link, my browser can take around a second to scroll to the target. This is a small paper cut but it adds up.

I finally figured out that this is due to bootstrap setting scroll-behavior: smooth (MDN reference for scroll-behavior). I'm aware that we can trivially override this in scikit-image and I intend to suggest that.

But I'm also wondering if using scroll-behavior: auto would be an improvement for this theme. If I understand correctly, animations can decrease accessibility and be disorienting. So it might be useful in that regard too. In any case, I don't understand the UX purpose of this animated scroll.

I'd be happy to do a PR for this. But if somebody already knows where the fix goes, please go ahead!

(Background reading: You dont need animations. That finally pushed me to investigate this issue.)

To disable, I think it would work to redefine $enable-smooth-scroll in https://github.com/pydata/pydata-sphinx-theme/blob/main/src/pydata_sphinx_theme/assets/styles/variables/_bootstrap.scss

Thanks for the pointer. I created #2261 as a first suggestion.
