Run Cypress tests with PreCompiledGenerator to make sure the asciidoc is generated

[nbaars]

Cypress now uses AsciiDocGenerator which uses on-the-fly conversion from asciidoc to html. For development this is a good as you change the asciidoc when developing a new challenge.

For the Cypress test the PreCompiledGenerator should be wired to let it run against the precompiled version. Maybe even better to only use this config when running a Maven build. Otherwise running from within IntelliJ might fail when developing a new challenge as the html files are only created when running Maven.
