typo in documentation

[MaSa759]

Hi,

I noticed a small mistake in the documentation file docs/en/configuration.rst:

wrong:

return [
     'doctrine' => [
         'entity_resolver' => [
             'orm_default' => [
                 'resolvers' => [
                     \Acme\InvoiceModule\Model\InvoiceSubjectInterface::class,
                     \Acme\CustomerModule\Entity\Customer::class,
                 ],
             ],
         ],
     ],
 ];

probably correct:

 return [
      'doctrine' => [
          'entity_resolver' => [
              'orm_default' => [
                  'resolvers' => [
                      \Acme\InvoiceModule\Model\InvoiceSubjectInterface::class => \Acme\CustomerModule\Entity\Customer::class,
                  ],
              ],
          ],
      ],
  ];

Thanks
