Add Data Explorer Python Polars Smoke Test

[jonvanausdeln]

Intent

Add Smoke test for Data Explorer using Python Polars

Approach

• Added new section to existing data explorer test. The new section is broken up into several it() blocks to cover multiple TestRail test cases.
• Added a console/runtime restart after the pandas test as the polars test uses the same variable names
• Added timeout to expect block in addFilter as it defaults to no timeout and could get stuck in loop.

QA Notes

Passes in Smoke CI
