Update

[ValupadasuSaiabbhiram]

Updated documentation markdown by replacing old icons with new ones (including freeware icon and money icon), and refined language for clarity.

Motivation and Context

This change improves readability and consistency in the documentation. Clearer icons help distinguish between open-source, freeware, and commercial software.

How Has This Been Tested?

Verified that icons render correctly in markdown preview and links work as expected. Checked visual consistency across different sections.
