Can we have a clearer error message than "Caused by: Missing font github"?

Problem

I just upgraded from 0.4.52 to 0.5.2 🚀 and mdbook build gave the following error message:

$ mdbook build
 INFO Book building has started
 INFO Running the html backend
ERROR Rendering failed
	Caused by: Error rendering "index" line 177, col 29: Missing font github
	Caused by: Missing font github

I found #2945 and changing git-repository-icon = "fa-github" to git-repository-icon = "fas-code-fork" in the book.toml file fixed the issue, but that error message was really confusing. Especially given that as far as I remember fa-github was suggested by the (previous) documentation.
Could that be improved?

If relevant this is the book.

I'm running into the same issue, and am confused why fa-github and fas-github don't work, since it's a free icon listed at https://fontawesome.com/v6/search where the changelog says to reference.

Edit: Ah, it's fab-github now, as mentioned in #2951.

It's fab-github with a b (for "brands").
