Colors for snacks highlights

[figmads]

Highlighting in snacks picker colors are incorrect. Looking at a similar issue, it seems like it's a theme shortcoming.

From the linked issue:

Just checked and they use the same hl group for NormalFloat and CursorLine.

We use Pmenu = DraculaBgDark for NormalFloat, so I don't think that's quite relevant. Rather, something there is using one of our subtler colors, which is effectively hidden when overlaying the CursorLine highlight.

The first step in solving this issue is to understand what groups snacks uses; the next is probably to provide support for it in the Plugins section by adding relevant tweaks.

Perhaps the docs will help identify the groups?

Contributions welcome ;) I don't have the bandwidth to dig into this personally.

I've fixed this in #341 but please feel free to change the colors from the ones I've selected.
