Change the type of the records manager to be the NodeViewCountRecordsManagerInterface instead of NodeViewCountRecordsManager

After receiving a request to retrieve the most viewed nodes per language, I endeavored to enhance the module's functionality by incorporating language support. To achieve this, I aimed to override the records_manager service using a custom class within a custom module. Additionally, I intended to augment the nodeviewcount table by introducing a new langcode column.

However, I encountered an obstacle as the NodeViewCountController constructor explicitly requires a first argument of type "\Drupal\nodeviewcount\NodeViewCountRecordsManager" and was thus unable to proceed with the modifications as planned.

That's why I thought it would be helpful if we can change this by switching the argument type from the class NodeViewCountRecordsManager to NodeViewCountRecordsManagerInterface ?

An initial patch has been uploaded for a starter point.
