[Bug] Clowning Around does not Check if the Pokemon Already has that Ability Before Granting It

[Snailman11]

Describe the bug

Clowning Around does not check if the Pokemon who you're attempting to teach a new Ability already has that Ability.

Reproduction

Change the Ability Override to reflect the one granted by beating the Clown.

	STARTING_WAVE_OVERRIDE: 11,

       // ABILITY_OVERRIDE: Abilities.BEAST_BOOST

	MYSTERY_ENCOUNTER_RATE_OVERRIDE: 255,

	MYSTERY_ENCOUNTER_OVERRIDE: MysteryEncounterType.CLOWNING_AROUND,

Expected behavior

It should probably disallow you from teaching an Ability to a Pokemon that already has it as their Ability or enabled Passive.
