doc(version): extensively revamp documentation for version subcommands

Enhanced and overhauled the documentation for the 'version' subcommand.
The improvements include comprehensive details on the subcommand's
behavior, usage, and a variety of scenarios it handles.

Added a central section within the pkgctl-version manpage that documents
the nvchecker configuration and rules.

Component: pkgctl version
