User description

💥 What does this PR do?

This PR updates Python's CI workflow:

• adds a new unit-tests job to run unit tests on Ubuntu/MacOS on the GH runners
• adds Chrome/Windows, Edge/Windows to the integration test browser/os matrix on the GH runners
• adds additional test target for Mac/Safari on the GH runners

This also fixes an assertion in a unit test that was broken on Windows.

🔧 Implementation Notes

We were not currently running any Python tests on Windows in CI. We have some Windows platform-specific code in the Python bindings and not all maintainers have a Windows system to test against.

💡 Additional Considerations

This might make the CI runs slightly longer.
