fix: cannot import text_unidecode, nemo-toolkit

[thundergolfer]

Describe your changes

Currently when Task tracing was turned on for a customer's modal.App the Task failed on startup due to errors in importlib machinery which do not occur normally.

The first issue was pypa/setuptools#4487. I could workaround that by doing setuptools==70.3.0 but then I hit other issues. Those other issues are fixed by the changeset here.

There's almost certainly more to understand about how an intercepting Loader should work but I think this change shouldn't introduce regressions.

nice! Are there any other methods in the Loader interface we need to implement?

I would bet that there is, but understanding what needs to be implemented is a matter of grokking a graph of like a dozen abstract base classes that comprises the importlib system.
