Test files appearing in distribution package

[slobberchops]

Describe the bug
The tests directory has been copied into the 2.3.2 distribution package. These files do not exist when downloading the 2.3.1 package. The existence of the test directory is likely unintentional and appears as a module when installed into a virtual environment.

This problem can be reproduced by creating a virtual environment and installing aiobotocore.

python3.9 -m venv aiobotocore
./aiobotocore/bin/pip install aiobotocore==2.3.2
 ls ./aiobotocore/lib/python3.9/site-packages/tests
... __init__.py  conftest.py       test_basic_s3.py  test_ec2.py	       test_mturk.py	 test_sns.py
... __pycache__  mock_server.py    test_batch.py	 test_eventstreams.py  test_patches.py	 test_sqs.py
... _helpers.py  moto_server.py    test_config.py	 test_lambda.py        test_response.py  test_version.py
... boto_tests   test_adaptive.py  test_dynamodb.py  test_monitor.py       test_session.py	 test_waiter.py

Installing 2.3.1 does not install the tests directory.

I also downloaded both 2.3.2 and 2.3.1 packages and verified that 2.3.2 contains tests whereas 2.3.1 does not.

Checklist

• I have reproduced in environment where pip check passes without errors
• I have provided pip freeze results
• I have provided sample code or detailed way to reproduce
• I have tried the same code in botocore to ensure this is an aiobotocore specific issue
• I have tried similar code in aiohttp to ensure this is is an aiobotocore specific issue
• I have checked the latest and older versions of aiobotocore/aiohttp/python to see if this is a regression / injection

pip freeze results

Environment:

• Python Version: 3.9
• OS name and version: Darwin

Additional context
As an aside, installation of tests as a module appears to cause some confusion with IntelliJ which then has trouble when working on a project that also uses tests as its test directory.
