Date inputs - `highlightToday` conflicting class names

[fbeceic]

Basic information

• Tiller version:
  1.13.0
• Module: date

Bug description

When enabling highlightToday prop, the look of the highlighted day is strange, with conflicting class names applied at the same time: text-primary-contrast and text-primary-dark. This causes the date to have the dark class name applied sometimes (depending on which class name is compiled first), resulting in a visually unappealing result (attached picture).

Expected behavior

Visually pleasing look of today's date (text-primary-contrast class name applied only) when selected and with highlightToday prop enabled on any date input.
