Problem: /documentation/* does not render because of quoting

The documentation contains Nix expressions, and they use the paired
single quote `''` extensively. Styx is not able to escape them, so
the content string terminates in the wrong place and the nix
expression becomes invalid.

Solution: Bump to fractalide/fractalide#155.

The quotes are escaped as HTML entities.
