Fix Strong Winds

MR Description

• Fix an issue occuring when the Strong Winds are set. They would cancel any move that is not super effective against a flying type.

Notes to acknowledge before testing

• Unlike the two others gen 3 beasts' weathers, Strong Winds doesn't cancel any move. However, it will lower the efficiency of a move that would be super effective against a flying type Pokémon.
• Note that a Pokémon with a dual typing such as Rayquaza-Mega that would make the move neutral (example: Thunderbolt is neutral because it is SE on flying, but resisted against dragon) also reduces the move's efficiency. Therefore, Thunderbolt against Rayquaza-Mega is resisted.

Tests to realize

• Ensure that a Super Effective move becomes Neutral when the weather is up, against a flying type.
• Ensure that a Neutral move becomes Resisted when the weather is up, against a flying type.
• Ensure that any other move against a Pokémon that is not flying type will act regardless of the weather.
