Docs: Add URL to rule documentation to the metadata (#10)

ESLint v4.15.0 added an official location for rules to store a URL to
their documentation in the rule metadata in eslint/eslint#9788. This
adds the URL to all the existing rules so anything consuming them can
know where their documentation is without having to resort to external
packages to guess.
