Bug Description

Python packages should not ship /usr/lib/python3/dist-packages/.pytest_cache

Recently, two packages python3-alembic and python3-astroid both shipped these files which collided on package install

dh-python has been improved upstream to stream all hidden "dot" directories in Debian #907871

This change should be imported and both alembic and astroid should be rebuilt (plus any other packages shipping this file)

It appears these packages are in main but mainly pulled in (at least on my system) by 'devscripts'. This affects cosmic.

Looks like the recent astroid rebuild/changes removed the file, but it's still present in alembic
