[PyPI] Replace Deprecated PyPI XMLRPC Methods in DataFed Python API

[suruihuang]

Description

DataFed currently uses deprecated XMLRPC methods from PyPI, which causes runtime errors on deployed sites.

Issue Details

When attempting to connect to PyPI, the following runtime error occurs:
Unable to connect to PyPI: <Fault -32500: 'RuntimeError: PyPI no longer supports the XMLRPC package_releases method. Use JSON or Simple API instead. See https://warehouse.pypa.io/api-reference/xml-rpc.html#deprecated-methods for more information.'>
Consider replacing deprecated XMLRPC methods with the current JSON or Simple API alternatives recommended by PyPI in python/datafed_pkg/datafed/MessageLib.py

Running returns this.

PYTHONPATH=. ./scripts/datafed

@suruihuang does this still let you continue using the client other than throwing the error? It should catch it and continue.

[JoshuaSBrown]

Confirmed that running client now does not trigger exception.

Looks like sort order is reversed by default.
