Update user's guide entry on demand analysis and worker/wrapper
The demand signature notation has been undocumented for a long time. The only source to understand it, apart from reading the `Outputable` instance, has been an outdated wiki page. Since the previous commits have reworked the demand lattice, I took it as an opportunity to also write some documentation about notation.
