Python: Bug: Please stop using deprecated/archived `nest_asyncio` package

[dagardner-nv]

Describe the bug
nest_asyncio has been archived by the owner for over a year now.

This has created problems with asyncio support in newer versions of Python and other packages which depend on these newer features. Specifically Python 3.12+ added an optional loop_factory parameter, however the patched version of asyncio.run from nest_asyncio's patched run method doesn't pass-through this keyword argument resulting in errors like:

> asyncio_run(amain(), loop_factory=get_loop_factory())
E TypeError: _patch_asyncio.<locals>.run() got an unexpected keyword argument 'loop_factory'

To Reproduce
Attempt to use newer asyncio features

Expected behavior
Don't patch the stdlib

Unfortunately we currently can't do without it for the Handlebars templates, so we either remove those, or we would need a new handlebars package that can call async functions.
