Fix dependency issues between boto3 and types-requests
boto3 has a dependency constraint urllib2<2
which is clashing with
recent types-requests (see
https://github.com/python/typeshed/blob/main/stubs/requests/METADATA.toml)
This ensures dependencies of swh.dataset do not get hit by this clash, making the dependecy solver of pip very slow (and selecting very old versions of some of these dependencies).
