[DOC]: Example of KNN graph generation

[mbruhns]

How would you describe the priority of this documentation request

Describe the future/missing documentation

It would be great to have a few examples/tutorials on how to generate a KNN graph (e.g., for Leiden clustering) based onNearestNeighbors from cuML. These example could cover different cases of (un)directed and (un)weighted graphs.
