ci: remove concurrency limits from integration and e2e test jobs

The reusable workflow `python_integration_tests.yaml` enforces
`concurrency: integration_tests` and `max-parallel: 1`, which meant
only one test matrix job could run at a time across both integration
and e2e suites.

Inline the job definitions to remove both limitations. All matrix
combinations now run in parallel.
