[Bf-docboard] Other projects wiki/sphinx migration

[Campbell Barton]

Recently I found this article about 2 other projects migrating from a
Wiki to Sphinx [0] for very similar reasons to us.

These are quite technical projects, and some of the pain-points we ran
into (build times and having to write our own tools in some cases)
aren't mentioned.
Nevertheless, interesting to see how other projects handle this.
