Minor Changes to run Example Training Files on the NuBench dataset

[christianlocatelli]

I ran one of the example training files on the low-energy Hexagon Ice Dataset and ran into 3 issues that I fixed.

1. I added the correct path to the module KNNGraph into 01_train_dynedge.py as the former path was labelled as outdated.
2. I added support for file paths with spaces into curated_datamodule.py for people like me with messy path structures and names.
3. I changed the order of the parameters "charge" and "t" in nubench_datasets.py, as this order is expected from the Hexagon detector's feature_map() in the detector model nubench.py.
