Transitioning from Flaticon to Fontawesome in Dokani theme.

**Description of the enhancement**

We currently utilize Flaticon on the front page of the Dokani theme. As we have already replaced Flaticon with Fontawesome in the Dokan plugin, we suggest enhancing the theme by replacing the Flaticon library with Fontawesome.
