update weaviate.py for weaviate compatibility (#2985)

File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/weaviate/schema/crud_schema.py", line 708, in _create_class_with_primitives
    raise UnexpectedStatusCodeException("Create class", response)
weaviate.exceptions.UnexpectedStatusCodeException: Create class! Unexpected status code: 422, with response body: {'error': [{'message': "'Auto-gpt' is not a valid class name"}]}.

GPT4:

The error message indicates that "Auto-gpt" is not a valid class name. In Weaviate, class names must start with a capital letter and can contain only alphanumeric characters.

Took advice and code and applying to weaviate.py to great result, programs runs now with no error!

Unable to reproduce easily. Might be related to switching memory between Local and Weaviate? Either way, the proposed solution works for MacOS using Docker + Weaviate.
