Description

This PR updates the version of Font Awesome used within the project from 6.5.1 Free to 6.5.2 Free. This adds additional characters.

The files are directly copied out of the published archive file with no alterations.

Please note that the CSS regeneration also seems to have pulled in the mastodon SCSS originally added in #885 - it looks like nobody regenerated the CSS during that PR. For what it's worth, a while back I did make a comment #864 about the fact that I have fully automated the CSS regeneration for my own branch using a Github action. You may want to consider it too (by which I mean 'tell me if you want it contributed back').
