[Help wanted] Enhance documentation with more examples of execution of `save-cli` with different initial configurations

For now we have a very pure information about general process of execution of some examples and its configuration

We have an directory with examples examples/kotlin-diktat, but it's not fully covered by readme's For any new user it's very uncomfortable to understand what's going on and how to execute save-cli with certain settings
