Add ligatures setting

The ligatures setting for historical ligatures has been added to the CSS
file. This modification enhances the typography of the project,
providing a more sophisticated and visually appealing text display. By
including font-variant-ligatures property with the value of
'historical-ligatures', the text now features ligatures that represent
combined characters, improving the overall readability and aesthetic of
the content.
