Update the Web families reference file (line_profile contract v2) #438

The DataLab copy of the Web families reference file (datalab/tests/features/hdf5/provenance_web_families.h5) records sigima.image.line_profile in contract version 1, refused since DataLab-Platform/Sigima#98: this operation is no longer replayed across editions from the Web file.

Update it from DataLab-Platform/web#72, which regenerates the file with the pinned Sigima snapshot (contract version 2).
