Update Font Awesome version

[gfairchild]

Would it be possible to update the Font Awesome version found here with this?:

    href="https://use.fontawesome.com/releases/v5.15.2/css/all.css"

As seen here, 5.15.2 is the latest release. The reason I ask is because I'd like to include the ORCID icon, which was added in version 5.11.0 and isn't available in the version in aafu at the moment.

I'm hopeful this'll be a pretty painless modification. I'm also happy to submit a PR if you'd like.

Thank you!
