📄 Description

Both NumPy and PyTorch do not allow operands of the matmul operation to be 0D tensors. To make TinyTorch achieve the same functionality as PyTorch, the method matmul should raise error when it receives a 0D tensor. For 0D tensor multiplication, users should use element-wise multiplication *.

All Tensor module tests pass and there is no regression.
