Fix incorrect documentation URLs when using rubocop --show-docs-url

[r7kamura]

Added DocumentationBaseURL for rubocop --show-docs-url [COP1,COP2,...] command to work correctly for rubocop-packaging cops.

Before

$ bundle exec rubocop --show-docs-url Packaging/BundlerSetupInTests
https://docs.rubocop.org/rubocop/cops_packaging.html#packagingbundlersetupintests

After

$ bundle exec rubocop --show-docs-url Packaging/BundlerSetupInTests
https://docs.rubocop.org/rubocop-packaging/cops_packaging.html#packagingbundlersetupintests

Hey @mvz,

@utkarsh2102 has regular merge been disabled?

Not really? I just enabled all 3 options. Isn't that what you see, too? 🤔

Bah! I did something stupid - I ticked "Require linear history" box and thus the issue. Fixed. Sorry. :(

Thanks for figuring this out @utkarsh2102. Seems like a GitHub UI issue to me 😄.

@utkarsh2102 This change only exists in the master branch for a long time. How about cutting a new version to RubyGems?
