[Inventory Management] `list_inventory` docstring summary needs improvement

[anym0us]

Docstring summary of list_inventory function is inconsistent.

A story behind

1. Initially I've started an implementation of list_inventory function based on docstring.
2. Wrote the function, run tests and found the implementation doesn't work.
3. Then read instructions and found inconsistencies between docstring and instructions.

Proposed change

Currently	Suggested
"""Create a list containing all (item_name, item_count) pairs in inventory.	"""Create a list containing only available (item_name, item_count > 0) pairs in inventory.
