Fixed incorrect argument: changed dims to dim

[framist]

I'd like to express my gratitude to the author for making your invaluable work open-source.

But when employing structure reparameterization on ModernTCN, the following error arises:

TypeError: cat() received an invalid combination of arguments - got (list, dims=int), but expected one of:
* (tuple of Tensors tensors, int dim, *, Tensor out)
* (tuple of Tensors tensors, name dim, *, Tensor out)

The bug is located in the PaddingTwoEdge1d method of the ReparamLargeKernelConv class. However, it erroneously employs the argument name dims instead of dim when invoking torch.cat, leading to this TypeError.
