Fixed hover background color issue

[hfactor13]

I fixed the hover background issue for the Translation Guide for the Python Packaging Guide (Issue #532). I also ran the nox docs-test command, and everything came back successful. Feel free to let me know if there's anything else I should include with this pull request.

I just realized that in the dark mode, the hover text looks a little bit hard to read, so I might edit that as well so that it is consistent across both light and dark modes.

I noticed that when I rebuilt the website, my light mode changes didn't show up. I rechecked the CSS variable --bs-body-bg, and it should be showing a white background for both light and dark modes. I remember I was able to get it to work in the sprints, but now it seems that I am back to square one it seems.

I am at keyboard again and can help with this, but the PR looks empty to me?

@hfactor13 i think something broke about this PR because i'm not seeing a diff, but i made a version over here: #556

sorry for the confusion. as far as i'm aware there is no way to use css vars in the plotly color declarations in some places, and these happen to be some of those places.

@sneakers-the-rat I see what you mean. Yes, it's weird that the diff didn't show in this PR. I saw your linked PR. I was planning to go in that direction where I would change the CSS directly, but I didn't know the name of the CSS tag. It's a bummer that I can't just change these properties from Plotly directly, but hey, at least I learned something new.
