v20.0.0 - TypeScript 2.7 support

• Breaking: the version of TypeScript supported by this plugin is 2.7.x (in line with typescript-eslint-parser’s TypeScript support)
• Updated dependencies that support the new ESLint documentation URL metadata. Errors from these plugins are accompanied by a link to the documentation for the broken rule.
• Dependencies are now strictly versioned for tighter control over the exact rules the plugin enforces.
