Rule proposal: require-meta-docs-url

[mysticatea]

Since eslint/eslint#9788, meta.docs.url is the official place to show the link to rule documentation. It would be good if there is a rule to enforce to write the link. Additionally, it's awesome if the rule is fixable.

{
    "eslint-plugin/require-meta-docs-url": [
        "error",
        { "pattern": "https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/{{name}}.md" }
    ]
}

• pattern (string) ... the URL pattern. Default is undefined. If this option is specified, the rule fixes meta.docs.url automatically. It replaces the {{name}} placeholder to rule name (path.basename(context.getFilename(), ".js")).

This could replace ESLint's internal consistent-docs-url rule, too.
