Noticed during #34778 that despite good coverage for the django-admin
commands in `tests/admin_scripts`, the coverage report suggests only 12%
coverage for `django/core/management/templates.py`.
This is because using coverage.py to trace code launched by a subprocess
(and not through multiprocessing) requires
[https://coverage.readthedocs.io/en/stable/subprocess.html additional
configuration], e.g. adding code to sitecustomize.py or creating a .pth
file.
Perhaps we could look into creating a tempdir with a .pth file to run the
needed coverage.py configuration while running tests.
