[FIX] website: adapt "Edit" and "Translate" systray items to dark mode

When the dark mode feature was merged with [1], it adapted the
EditWebsiteSystray item with the 'text-reset' class.

But this class was not removed if the website was translatable, and it
was not added on the TranslateWebsiteSystray item, which was leading to
wrongly colored systray items on a translatable website.
