12735 update endpoint that sets datatype for process task to accept array of data types

[standeren]

Description

Use same event but wrap the newDataType inside an array. Change type of newDataType in backend also to be an array and loop through it before doing the same operations on all the individual dataTypes. Before setting the taskId for all the dataTypes, we iterate over the dataTypes that has the connected task from before and remove the taskId from all.

Currently not implemented any logic to identify which of the dataTypes that should be connected in the layoutsets-file. Simply select the first in the list
