What happened?

This odd set of regexes determines what goes into the info- portion of a .conda versus the pkg- portion. https://github.com/conda/conda-package-handling/blob/main/src/conda_package_handling/utils.py#L438

It has some obvious mistakes. (Did not attempt to change it at the same time as the 2.0 release, for compatibility.)

We could audit the existing packages to see if we can use a simple "starts with info/" rule instead of whatever this is.

The part that filters .DS_Store etc. should stay.
