networkx version issue

[tsalo]

          Thank you. I tried the same call as above with the aslprep:unstable image, and now receive the following: 

230301-15:15:21,481 nipype.workflow IMPORTANT:
         ASLPrep started!
230301-15:15:21,854 nipype.workflow CRITICAL:
         ASLPrep failed: module 'networkx' has no attribute 'to_scipy_sparse_matrix'

This seems to be related to this change to Networkx with version 3.0: https://networkx.org/documentation/latest/release/migration_guide_from_2.x_to_3.0.html#replacing-numpy-scipy-matrices-with-arrays
