`BUGFIX: Add missing content type header to create-image-variant endpoint <https://github.com/neos/neos-development-collection/pull/5762>`_
-------------------------------------------------------------------------------------------------------------------------------------------

### Upgrade instructions

Currently, the enpoint ``/neos/content/create-image-variant`` does not set a ``Content-Type`` header and therefore uses the default ``text/html`` content type. This can lead to issues, if any of the used middlewares require a correct content type to be set. One example could be that you have a middleware that will add an attribute to all ``<script>``-Tags if the returned content type is ``text/html``. When using the php `DOMDocument <https://www.php.net/manual/en/class.domdocument.php>``_ or sth. similar to parse and update the content, this will result in the response being wrapped by a ``<p>`-Tag and therefore returns an error.

### Review instructions

To test this behaviour:

- Add a new middleware.
- Add sth. like the following to this middleware:
  ```php
  use GuzzleHttp\\Psr7\\Utils;
  
  // ...
  
  public function process(ServerRequestInterface $request, RequestHandlerInterface $next): ResponseInterface
  {
      $response = $next->handle($request);
      
      if (str_contains($response->getHeaderLine('Content-Type'), 'text/html')) {
          $content = $response->getBody()->getContents();
          
          // This is one case, that could result in an issue with the current state.
          $dom = new \\DOMDocument();
          libxml_use_internal_errors(true);
          $dom->loadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
          libxml_use_internal_errors(false);
          
          $scripts = $dom->getElementsByTagName('script');
          foreach ($scripts as $script) {
              $script->setAttribute('x-custom-attribute', 'some-value');
          }

          $newContent = $dom->saveHtml();
          
          $response = $response->withBody(Utils::streamFor($newContent));
      }
      
      return $response;
  }
  ```
