We replace the default bootstrap `text-<color>`
utility CSS classes with an own color-scheme
aware implementation.

In contrast to the original bootstrap color
utilities we ensure that the new set is
accessible and optimize the color contrast
for all values. This results in darker colors for
light-mode and lighter colors for dark-mode.
