Removed duplicate property definitions in CityLearnEnv class

[LucasNH]

Description

Removed duplicate property definitions in CityLearnEnv class, removed trailing whitespace.

Issue

Duplicate definitions of the following properties in the CityLearnEnv class:

• net_electricity_consumption_cost_without_storage (different return type: .tolist() rather than .to_numpy())
• net_electricity_consumption_emission_without_storage (exact duplicate)
• net_electricity_consumption_without_storage (exact duplicate)

Original definitions in lines 629-654, duplicate definitions in lines 656-681.

(base) ~ % sed -n '628,682p' citylearn/citylearn.py | grep 'def ' | sort | uniq -d def net_electricity_consumption_cost_without_storage(self) -> np.ndarray: def net_electricity_consumption_emission_without_storage(self) -> np.ndarray: def net_electricity_consumption_without_storage(self) -> np.ndarray:

Changes

• Removed duplicated definitions; favoured definitions consistent with return type (only relevant for net_electricity_consumption_cost_without_storage),
• Removed trailing whitepsace.
