Rename the following labels:
Cancel running process instances --> Delete running process instances
Delete finished processes --> Delete finished process instances
Set retries of Jobs belonging to the process --> Set retries of Jobs belonging to the process instances

For Delete running process instances it is necessary to rename the Cancellation reason label to Delete Reason

Reason:
As we perform the operations on process instances we should make this clear.
Furthermore for deletion the REST-Endpoint is called "/camunda/api/engine/process-instance/delete-historic-query-based". This "deletion" semantic should be reflected in the frontend to avoid confusion for the user
