No need to set initial position in EnemySpawner

[Asherat]

Since the initial position is already set in the Start() method of Pathfinder, it is not necessary to set it again in EnemySpawner.
Here is an optimized version:

    void SpawnEnemies()
    {
        for (int i = 0; i < currentWave.GetEnemyCount(); i++)
        {
            Instantiate(currentWave.GetEnemyPrefab(i), transform);
        }
    }
