Chrome shouldn't be closed when using Chrome service

[brusch]

Currently the browser gets closed after rendering here:
https://github.com/pimcore/web-to-print-bundle/blob/1.x/src/Processor/Chromium.php#L139

Actually this causes issues when using Chrome as as a container service, e.g. ws://chrome:3000/

The following patch fixes the issue:

diff --git a/src/Processor/Chromium.php b/src/Processor/Chromium.php
index dafc77c..4d1b25a 100644
--- a/src/Processor/Chromium.php
+++ b/src/Processor/Chromium.php
@@ -136,7 +136,7 @@ class Chromium extends Processor
             Logger::debug('Could not create pdf with chromium: '. print_r($e, true));
             $output = (string) $e;
         } finally {
-            $browser->close();
+            $page->close();
         }

         return $output;
