Per a comment from @mesejo in #880 it would be helpful to run user examples in CI to ensure that our examples stay up to date with any breaking changes in the API.
Describe the solution you'd like
Update all user examples if necessary and add code to run them as part of CI.
Describe alternatives you've considered
We could leave as is, but this seems like a very good idea.
Additional context
This is already being done for TPC-H queries and we can re-use the generated dataset that is already created in CI. Here is where the tests are being run: https://github.com/apache/datafusion-python/blob/main/examples/tpch/_tests.py
