(#1028) Update icons with font awesome accesibility approach

[LeaDevelop]

Description Of Changes

Unicode emoticons (⚙💾🔍➕📅🗑) replaced with font awesome accessibility ones.

Motivation and Context

Motivation was to improve the user experience and ensure consistent visual representation across different platforms and devices. Previously, emoticons were not considering accessibility, which could lead to confusion or misinterpretation of the documentation when using screen reader.
