Remove unused squeeze from VJEPA2 embeddings rotation

[materight]

What does this PR do?

Removes unused .squeeze from VJEPA2 embeddings rotation. Currently the squeeze does nothing on video input since torch skips it if the dimension is not 1. Exporting to onnx and compiling to TensorRT instead fails because the squeeze is mantained.
