What operation is being done to the arr[i], arr[i+1] in the second line.

arr[i], arr[i + 1] = arr[i + 1], arr[i] means value swapping to sort the array.

arr = [3,2]
i = 0
arr[i], arr[i + 1] = arr[i + 1], arr[i]
arr # => [2,3]

What's this type of ternary called?

This is called parallel assignment,not ternary.
