Follow Python coding guidelines

[pamelafox]

This is a subset of the guidelines from https://github.com/Azure-Samples/samples-guidelines/blob/main/python-guidelines.md

• [ ] Use ruff for linting and either black or ruff for formatting, per https://github.com/Azure-Samples/samples-guidelines/blob/main/python-guidelines.md#92-code-quality
• [ ] Add CI/CD that runs the lint and format check
• [x] Add dependabot for version updating
• [x] Use version pinning and dependabot, per https://github.com/Azure-Samples/samples-guidelines/blob/main/python-guidelines.md#dependencies
• [x] Use a logger, not print calls, per https://github.com/Azure-Samples/samples-guidelines/blob/main/python-guidelines.md#94-monitoring
