zipapp docs should not suggest deleting .dist-info subdirectories #107322
Description
From Creating Standalone Applications with zipapp, point 3 mentions you may delete .dist-info directories "as you won’t be making any further use of pip they aren’t required".
But you can have a nasty surprise this way - the problem is that this totally breaks importlib.metadata usage.
E.g. if you have an argparse --version in your app which uses importlib.metadata.version("myapp"), but you've unlinked all the .dist-info metadata before making the zipapp, you'll get:
importlib.metadata.PackageNotFoundError: No package metadata was found for myapp
We don't know if/when third party libraries want to look at their own package metadata, so I think this suggestion in the docs should be removed outright.
