Fix [BUG] #5081 Wrong visual text when using priority moves on Psychic Terrain

[KennethWest]

What are the changes the user will see?

When battling on Psychic Terrain the user will now get battle text that properly reflects which Pokémon was protected from a priority move blocked by the terrain.

Why am I making these changes?

Currently the text says the user of the move is protected by the Psychic Terrain, that can be confusing for players. More over it withholds information from the player about which Pokémon is being targeted by the opponent in double battles.

Fixes #5081

What are the changes from a developer perspective?

All changes occurred in src/phases/move-phase.ts. Changed the arguments passed to the function getTerrainBlockMessage().
Previously the argument list was:
getTerrainBlockMessage(this.pokemon, this.scene.arena.getTerrainType()) which would pass the Pokémon that used the move along to rather that the target of the move.
It was changed to:
getTerrainBlockMessage(targets[0], this.scene.arena.getTerrainType()).

How to test the changes?

My overrides.ts file only gave Pokémon the psychic surge ability and priority moves to test. Separate tests forced opponent move sets to have priority moves as well. Didn't feel the need for automated tests, and there are no special requirements to test if this works.

I'm not sure this is applicable at the moment, since by current definition Psychic Terrain cannot block moves that target multiple or adjacent Pokémon even if they become priority moves.
