Require Python 3.9+, test for 3.9 and 3.11 (#1924)

Summary: ## Motivation Python 3.11 was released over 8 months ago, so we should be testing for it. We can also drop support for Python 3.8, which was supplanted by 3.9 nearly 3 years ago. ### Have you read the [Contributing Guidelines on pull requests](https://github.com/pytorch/botorch/blob/main/CONTRIBUTING.md#pull-requests)?
