Upgraded to Python 3.11

The Listen Notes backend is running Python code. We just upgraded our Python runtime from 3.10 to 3.11. And we saw ~10% overall performance improvement instantly!

We could’ve made the upgrade earlier, but it was blocked by some 3rd party packages that had not supported 3.11.

The last blocking dependency was clickhouse-driver. So I created a GitHub issue in the repo. A few days later, the developer finally made clickhouse-driver Python 3.11-ready. Happy!
