feat(version): add command to automatically detect and setup nvchecker

Introduce a new version subcommand `setup` which does a best effort to
generate the most minimal required .nvchecker.toml file for specific
sources.

It supports a wide range of common sources like:
- Git, GitHub, GitLab, Hackage, NPM, PyPI, RubyGems, CPAN, crates.io

The creation logic is based on matching a domain for a source which is
something predictable and then simply passes an array of the url parts
for every source creator to extract the useful bits out of the url
array.
