Read from Font Awesome Solid rather than Font Awesome 4

[apriltaoyvr]

Clear and concise description of the problem

The extension reads icons from the Font Awesome 4 (https://icones.netlify.app/collection/fa) collection of Netlify rather than the Font Awesome Solid (https://icones.netlify.app/collection/fa6-solid) collection.

Because the FA4 collection only contains around 500 icons while the FAS collection contains 1.2k, there are many icons not being previewed.

Suggested solution

Read from the Netlify FAS collection instead of FA4.

Alternative

No response

Additional context
