Bug in Drag and Drop Interaction

[rt4914]

Describe the bug
In Drag and Drop Exploration, if I pin all options and click on submit nothing happens and submit button becomes inactive.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'ExplorationRetriever'
2. Map drag_and_drop_test_exploration.json (or) test_exp_id_4 such that it can be opened from any story.
3. Now, pin all options such that it look similar to the screenshot
4. Click submit
5. See error - > Submit button will become inactive.

Expected behavior
Either there should be proper error message or some something to make sure that it does not look incomplete.

@BenHenning if you remember there was a change in the name of one classifier rule

oppia-android/domain/src/main/java/org/oppia/domain/classify/rules/dragAndDropSortInput/DragDropSortInputModule.kt

Line 39 in 0b6b6f7

@StringKey("IsEqualToOrderingWithOneItemIncorrect")

and on the web we are still using the old name as per this json file

oppia-android/domain/src/main/assets/test_exp_id_4.json

Line 130 in 0b6b6f7

"rule_type": "IsEqualToOrderingWithOneItemAtIncorrectPosition",

We should ensure web & Android are consistent here, and that all of Android's local files are correct.
