Subject: [PATCH] fix: allow config file to load `showLineNumbers`

- Added in a fix to allow the `showLineNumbers` config option to
  be loaded from the config file
- Previously it seems unclear on how to setup the `showLineNumbers` key
  within the config, and while there was support added for configuring
  the `showLineNumbers` flag, it couldn't be read from the config file,
  since the `validateOptions` method would not retrieve the key from
  the config file
- Hence changed it so that it does retrieve the `showLineNumbers` key
  from the config file, and use it as needed
- Updated the README.md to also provide an example on how to setup
  both the keys
