This is a small PR that attempts to solve the issue #4440.
But in the wiki there are two FAQ links:
1. https://wiki.freecadweb.org/FAQ/en
2. https://wiki.freecadweb.org/Frequently_asked_questions
Both have almost the same contents but the 1st one more translated so I have used that link to fix the broken link.
I noticed that all the wiki links in the README use redirects from www.freecad.org/wiki/ -> wiki.freecad.org, is that intentional or just some legacy stuff?
[PR #3925] Fixed broken FAQ link in README, resolves #4440
