Configuration guide should be generated from code

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
The user guide contains a hand-maintained (and therefore, probably outdated) config guide.

**Describe the solution you'd like**
Generate the config guide from the source as a GitHub workflow when publishing the docs, so that it is always up-to-date

**Describe alternatives you've considered**

**Additional context**
