As described in #351, there was the possibility for a DimensionMismatch error due to the non-zero default rank_atol in MatrixAlgebraKit's SVD pullbacks. Here I set rank_atol=0 explicitly for FixedSVD and IterSVD pullbacks, so that error shouldn't happen again.

I'm not quite sure how to test this, so if anybody has an idea, let me know.

Will close this since it should be fixed by QuantumKitHub/MatrixAlgebraKit.jl#208
