When "nord2" color is used in ui.selection it is almost invisible
if cursorline highlighting is enabled. Changing the color to "nord3" fixes the issue.
* add jump-label styling for base16_transparent theme
* keep the change consistent with other themes from base16 family
* update jump-labels color to blue and make them bold
Before the fix, the color that the original (Neovim) tokyonight uses for
Neovim's visual mode was used in Helix for highlighting the selected
item in the picker. But for the highlighting of selected _text_ in
Helix (corresponding to Neovim's visual mode), a much darker background
was used. This made it very hard to pick out selected text, in
particular in suboptimal lighting conditions.
I swapped the two colors, so that text selection now looks like in
Neovim, while selected items in the picker are highlighted a bit less
strongly. (But still easy to see because the whole line is highlighted.)
