Generate hashes covering the PyPi index as well as additional candidates available through an extra index of find-links. Currently if PyPi index is available the hashes will be limited to those available in it.

Contributor checklist

• Provided the tests for the changes.
• Assure PR title is short, clear, and good to be included in the user-oriented changelog

Maintainer checklist

• Assure one of these labels is present: backwards incompatible, feature, enhancement, deprecation, bug, dependency, docs or skip-changelog as they determine changelog listing.
• Assign the PR to an existing or new milestone for the target version (following Semantic Versioning).

@atugushev wdyt about the current test coverage?
I've had a failing test on Python 3.11 so I added a couple of troubleshooting lines to get more details.

That's because it's been installed from sdists from PyPI (note "Downloading torch_scatter-2.0.9.tar.gz"), which has import torch in setup.py. Note, there are no wheels for Python 3.11 in https://data.pyg.org/whl/torch-1.13.0+cpu.html.

With others Python version works fine, because they've been installed from wheels from https://data.pyg.org/whl/torch-1.13.0+cpu.html

That's looking better, thanks for the help on the test side @atugushev.
