[MCPE-181433] Duplicate unused Trial Spawner textures in vanilla

In the textures/blocks folder in the 1.21.0 resources, there are duplicate files for three Trial Spawner textures. The duplicates are unused and should be removed. The Ominous Trial Spawner is not affected by this issue.

Correct Texture	Duplicate, Unused Texture	Java Texture
trial_spawner_side_active	trial_spawner_side	trial_spawner_side_active
trial_spawner_top_active	trial_spawner_top	trial_spawner_top_active
trial_spawner_top_ejecting_reward	trial_spawner_top_open	trial_spawner_top_ejecting_reward

Expected Result

There is only one file for each texture.

Observed Result

There are two identical files for each texture listed in the table above.

To Fix

Just delete the textures in the Duplicate, Unused Texture column. They are not used by the game.
