Add an item to the end of a list (aka Push).
This function can operate on lists of any type. To ensure this works correctly, you should make sure that all 3 fields are set to the same type, i.e. if you want to process a list of text, set both list fields to be a list of text and set the item input to be type text.
- list: the input list
- item: the item to add
- list: a new list which is the input list with item added to the end.
