Unclosed coonnection

[maretodoric]

Describe the bug

Unclosed connection
client_connection: Connection<ConnectionKey(host='bucket-name.s3.eu-central-1.amazonaws.com', port=443, is_ssl=True, ssl=None, proxy=None, proxy_auth=None, proxy_headers_hash=None)>

Warning shows up when using S3 client, get_object method.

This is the code I've used:

async def get_s3_object(bucket: str, filepath: str):
    filepath = str(filepath)
    cfg = load_settings()

    session = get_session()
    async with session.create_client('s3', region_name='eu-central-1',
                                     aws_secret_access_key=cfg.aws.secret_key,
                                     aws_access_key_id=cfg.aws.key) as client:
        # get object from s3
        try: s3_ob = await client.get_object(Bucket=bucket, Key=filepath)
        except Exception as e:
            if type(e).__name__ == 'NoSuchKey':
                raise FileNotFoundError(f"File '{basename(filepath)}' not found in bucket: '{bucket}'.")
            else:
                raise
        if s3_ob['ResponseMetadata']['HTTPStatusCode'] != 200:
            raise Exception(f"HTTP Status Code invalid. Response: {s3_ob}")
        else:
            return S3Object(bucket, filepath, s3_ob['ContentLength'], s3_ob['ContentType'])

Checklist

• [x] I have reproduced in environment where pip check passes without errors
• [x] I have provided pip freeze results
• [x] I have provided sample code or detailed way to reproduce
• [x] 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 wouldn't know how to replicate this with aiohttp
• [x] I have checked the latest and older versions of aiobotocore/aiohttp/python to see if this is a regression / injection

• OS name and version: Ubuntu 22.04

Additional context I've first noticed this when using aioboto3, however when i was told to try and replicate this with aiobotocore - i did and it can be replicated. Warning itself doesn't appear to cause any issues but potential high number of unclosed connections could pose an issue.
