QTI 2.1: select formative/summative default in options

in the options of QTI 2.1 tests (in the learning resource) a default setting for formative and summative tests can be chosen.

--> display should be changed to dropdown (see screenshot)
(take same wording as already exist)
--> sentence is added:
You can chose a default setting for summative or formative tests and adapt it afterward or you set the options by yourself.
Sie können die Standardeinstellung für summative oder formative Tests übernehmen und anpassen oder Sie setzen die Optionen selbst.
