Add eslint-plugin-eslint-plugin and add URLs to all rules

[ddzz]

This PR adds eslint-plugin-eslint-plugin and its recommended rules to this plugin so that ESLint catches common issues found in ESLint plugins.

You'll want to add the rule format so that the correct rule URLs can be enforced and autofixed:

Suggested change

	"eslint-plugin/require-meta-docs-url": "error"
	"eslint-plugin/require-meta-docs-url": ["error", {
	"pattern": "https://github.com/cypress-io/eslint-plugin-cypress/blob/master/docs/rules/{{name}}.md"
	}],

[ddzz]

Some rules don't use documentation from GitHub, so this pattern can't be used.

[bmish]

I see. If it's just one rule, then it would probably be good to still use the pattern globally, but just disable the rule for that specific edge case:

url: 'non-github-url' // eslint-disable-line eslint-plugin/require-meta-docs-url

[ddzz]

1/3rd of existing rules don't use GitHub docs. eslint-disables will just clutter up the rules.

[bmish]

Adding a type to a rule is a trivial one-line change so would be good to add types instead of disabling this.

	"eslint-plugin-eslint-plugin": "^4.0.1",

Can you bump to v4 which was just released today?
