Import redis.connection.BaseParser instead of from untyped module

I was getting errors when running stubtest locally:

➤ bash ./scripts/stubtest.sh
error: not checking stubs due to mypy build errors:
django-stubs/core/cache/backends/redis.pyi:7: error: Library stubs not installed for "redis._parsers"  [import-untyped]
django-stubs/core/cache/backends/redis.pyi:7: note: Hint: "python3 -m pip install types-redis"
django-stubs/core/cache/backends/redis.pyi:7: note: (or run "mypy --install-types" to install all missing stub packages)
django-stubs/core/cache/backends/redis.pyi:7: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports

Not sure if it could be related to the new release of types-redis from ~12h ago: https://pypi.org/project/types-redis/4.6.0.20240417/

Though I'm finding the DefaultParser / BaseParser from redis declared at:

• https://github.com/python/typeshed/blob/6e16a4ce23235d5ba8ebd2adcd32f7d62f509dbe/stubs/redis/redis/connection.pyi#L73
• https://github.com/python/typeshed/blob/6e16a4ce23235d5ba8ebd2adcd32f7d62f509dbe/stubs/redis/redis/connection.pyi#L32-L35

And I think that aligns with Django's runtime usage, found here:

• https://github.com/django/django/blob/476d7c581ac97dae2bc14ee79a1294db4f802e74/django/core/cache/backends/redis.py#L59

Nvm this, just figured out we shouldn't use types-redis from this #1948 (comment)
