MAINT: add 3.11 test

[homosapien-lcy]

With new python tests, we also want to test and make sure all examples can work in 3.11. Since 3.11 is not available in EDM, pypi is tested. closes #860

An error happened when running on python 3.6 which is similar to what happened in SciMath (https://github.com/enthought/scimath/issues/170)

Problem description: If python 3.6 is added to the pypi test, it will generate a "The version '3.6' with architecture 'x64' was not found for Ubuntu 22.04." error.

Reproduction steps: Add 3.6 to .github/workflows/test-with-pypi.yml.

Expected behavior: Pass the github workflows test.

OS: Ubuntu 22.04

Python version: 3.6

The tests with other python versions are past though

python3.11 -m pip install -e .

You probably should be doing python3.11 -m pip install -e ".[examples]" or something similar to bring in pandas and scipy example dependencies.

Hi Corran: thanks for the advice. Could you give an example of what should be in the ".[examples]"? This repositery for instance
