[FIX] theme_*: adapt xpath for s_timeline(_images, _list) changes

*: theme_artists, theme_buzzy, theme_nano

Before, the timeline (*) dots were invisible when using preset 4
because they shared the same color as the background (`text-o-color-1`
on `o-color-1` background).

The fix in the relative PR implements a solution that ensures dots are
always visible by using button primary colors for all presets.

Thus, this commit adapts xpath to ensure compatibility with the changes.
