[ty] Fix namespace packages that behave like partial stubs (#19994) In implementing partial stubs I had observed that this continue in the namespace package code seemed erroneous since the same continue for partial stubs didn't work. Unfortunately I wasn't confident enough to push on that hunch. Fortunately I remembered that hunch to make this an easy fix. The issue with the continue is that it bails out of the current search-path without testing any .py files. This breaks when for example `google` and `google-stubs`/`types-google` are both in the same site-packages dir -- failing to find a module in `types-google` has us completely skip over `google`!
