Python: No more hardcoded Azure OpenAI Service deployment name (#2684)

### Motivation and Context

Solve confusion due to hardcoded Azure OpenAI Service deployment name in
Python notebooks.

<!-- Thank you for your contribution to the semantic-kernel repo!
Please help reviewers and future users, providing the following
information:
  1. Why is this change required?
  2. What problem does it solve?
  3. What scenario does it contribute to?
  4. If it fixes an open issue, please link to the issue here.

### Description

Previously, the deployment name for Azure OpenAI Service in the Python
notebooks was hardcoded as "gpt-35-turbo".
This PR solves the confusion by using the `deployment` variable loaded
from `.env` file.

<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->
