Important: #105538 - Plugin subtypes removed: Changes to configurePlugin() and TCA handling 

See forge#105538

Description 

Due to the removal of the plugin content element "Plugin" (list) and the corresponding plugin subtype field list_type , the fifth parameter $pluginType of ExtensionUtility::configurePlugin() is now unused and can be omitted. It is only kept for backwards compatibility.

Be aware that passing any value other than CType will trigger an \InvalidArgumentException .

Please also note that due to the removal of the list_type field in tt_content , passing list_type as the second parameter $field to ExtensionManagementUtility::addTcaSelectItemGroup() will now, as for any other non-existent field, trigger a \RuntimeException .
