package/python-botocore: bump to version 1.31.20

When we bumped urllib3 in 074bc42971181ee71d8ff5bd57641b7b7eb7580f
we broke compatibility with python-botocore.

This compatibility error was fixed upstream in botocore 1.29.122:
https://github.com/boto/botocore/commit/0a6d8e3c6325da395a04227599cfa292190d6841
