Pelican-bootstrap3 doesn't seem to support newer versions of fontawesome

[finite9]

Mastodon icon doesn't work, but things like twitter, youtube etc work fine. I googled it, and it might be same issue as this:

nairobilug/pelican-alchemy#69

The Mastodon icon seems to have appeared in fontawesome after version 5.0.11, so fontawesome in pelican-bootstrap3 must be below that I guess. That issue is from 5 years ago, which makes me think this theme isn't actively developed anymore?

Is it possible to add this like pelican-alchemy has done:

FONTAWESOME_CSS: URL of Font Awesome CSS file. Use this if you wish to use CDN provided version instead of the bundled one.
