Issue with new release of aioboto3 9.0.0

[vkuna]

When upgraded to aioboto3 version 9.0.0 the script returns this error:

AttributeError: module 'aioboto3' has no attribute 'client'

The last version of aioboto3 that is working well is 8.3.0

Hi, I've created #17 to change how the aioboto3 client is created.
