feat(docs): use custom defaults during docs generation (#2022)
* remove docs generator code from step-generator

* add docs generator to dedicated package

* add test cases

* add entry point for docs generation

* make output more readable

* read additional defaults

* add custo defaults parameters

* remove commented code

* adjust custom default parameter in workflow

* remove conflict leftovers

* handle custom default values

* remove comment

* extract code to function

* extract metadata reading to function

* do not print empty strings in favor of PIPER_* env vars

* extract new code to own metadata file
