Faster documentation generation (#2722)

* Get rid of cli and core dependency for generator

* Remove generic argument parsing made for sharing but introduced complexity

* Do not use expensive shadow plugin on internal generator module

* Apply shadow plugin for cli in packaging

* Generate documentation after compilation of rules

* Trigger generateDocumentation when formatting rules are changed

* Further reduce complexity of parsing args

* Start generateDocumentation directly from gradle

* Test additional error paths of CliArgs
