Update Fontawesome Solid Icons

[tonamphong]

Hi @hexplor
Can you update the Fontawesome Solid icons ? Example the old fa-solid-900.woff2 file (https://github.com/gantry/gantry5/tree/develop/assets/common/webfonts) is 80kb and the new fa-solid-900.woff2 is 156KB. Using Joomla 5, Gantry5 CI build, some icons are missing like fas fa-desktop and fas fa-cloud-download-alt, if I replace the new file, the icons will appear.
