Why

docs/config.md basically mixed the usage of options that is only used by different cz commands together. It would be better if those options are categorized.

Also, duplication of option usage documentation occurs. It should be fixed.

This PR categorized and centralizes those configuration file options, and remove the duplication of option usages.

The configuration file doc and version provider doc have their own pages now.
