release: Fix build of the manual

The changes in NixOS/nixpkgs@4b4bbce199d3b3a8001ee93495604289b0
include moving the style.css to a different location, but they also add
syntax highlighting, so let's include it as well :-)

I've also reorganized the XSLT flags a bit and instead of a big
multiline string we now use an attribute set to define these flags in a
declarative way.
