output ForceFieldStructureTaskDocument or ForceFieldMoleculeTaskDocument based on the input type of mol_or_struct.

change name ForceFieldTaskDocument => ForceFieldStructureTaskDocument

output ForceFieldStructureTaskDocument or ForceFieldMoleculeTaskDocument based on type of mol_or_struct

update ForceFieldTaskDocument => ForceFieldStructureTaskDocument in the tests

import Union from typing

include Union in forcefield/md.py

take the suggestions from the formatter

take ruff's suggestions

try again with ruff format

ruff format again

try again ruff

ruff again

fix the mypy error

Take inputs of both Molecule and Structure

update docstring

add molecule test for forcefield
