ci: run integration test on more python version (#2400)

# What does this PR do?
Expand the test matrix to include Python 3.10, 3.11, and 3.12 to ensure
the project runs correctly on these versions. This will give us
confidence to begin considering an increase to the project's minimum
supported Python version.
