feat: add array support on main prompt (#1503)

* prompt array support

* update change log

* update change log

* docs: remove 2.1.847 change log

* refactor: rename freeze_seed to disable_seed_increment, move to developer debug mode

* feat: add translation for new labels

* fix: use task_rng based on task_seed, not initial seed
