[Accessibility] Hover link color in dark mode has insufficient contrast

[jaimergp]

What happened?

This theme redefines carefully chosen defaults in the color palette to account for accessibility issues like contrast. The colors chosen are on brand with the conda ecosystem, and that's great, but there are some nuances that need to be taken into account to keep the accessibility features of the original theme.

For example, hover links color in dark mode is tricky to see:

This can be further assessed with the Chrome dev tools. Those horizontal curves in the color map are the minimum thresholds for AA and AAA; above means passing it, below means insufficient contrast.

Thanks for finding this. I don't use dark theme ever, which is why I missed it. Should be easy enough to fix.
