Python: Add AI connector README

[TaoChenOSU]

Motivation and Context

We need a README in the connectors/ai directory to list all the existing AI connectors.

Description

Contribution Checklist

1. Add a README
2. Refactor some connector package paths

• The code builds clean without any errors or warnings
• The PR follows the SK Contribution Guidelines and the pre-submission formatting script raises no violations
• All unit tests pass, and I have added new tests where possible
• I didn't break anyone 😄
