PyPI's XML-RPC is deprecated

[webknjaz]

Got this in CI half an hour ago:

Exception occurred:
  File "/opt/hostedtoolcache/Python/3.11.9/x64/lib/python3.11/xmlrpc/client.py", line 668, in close
    raise Fault(**self._stack[0])

Use the Simple API to query for list of project names with releases on PyPI.

A CI job rerun succeeded. So they've probably configured hard failures for a certain percentage of requests. FYI.

It doesn't seem like it can be replaced with JSON API. Perhaps, it's possible to grab this data from the BigQuery dataset instead: https://warehouse.pypa.io/api-reference/bigquery-datasets.html / https://packaging.python.org/en/latest/guides/analyzing-pypi-package-downloads/.

Meanwhile, I suppose the current workaround is spelling_ignore_pypi_package_names = False.

The endpoint is now gone for good: https://mail.python.org/archives/list/[email protected]/message/5YFJHGOTOUBJJ5ZSFKGN3ABVN4Y7AJ4K/

It sounds like that feature should be disabled by default until it's clear what alternatives might exist. I'm not likely to have time to do anything about that for a while, but if someone was to submit a PR I could review it.

This fix is included in release 8.0.1.
