This pull request reorganizes and clarifies the GitHub Actions workflows for testing, specifically separating out "contrib" tests from other Python tests and improving how test paths are handled for various frameworks. The changes rename workflow files, update job and matrix naming conventions, and enhance test execution logic to include both integration and unit tests where applicable.

Workflow renaming and restructuring:

• Renamed .github/workflows/integration-tests.yml to .github/workflows/contrib-tests.yml and updated naming conventions throughout the workflow to use "contrib" instead of "integration".
• Updated matrix definitions in the contrib_matrix job to use contrib as the key, and added explicit paths for integration and unit tests for each framework.

Test execution improvements:

• Enhanced the test execution step in contrib-tests.yml to dynamically include both integration and unit test paths if they exist, allowing for more comprehensive testing per framework.

Coverage reporting updates:

• Updated Codecov upload flags and naming to reflect the new "contrib" terminology and matrix structure.

Python tests workflow update:

• Modified the Python tests workflow to ignore both tests/integration/contrib and tests/unit/contrib directories during standard test runs, ensuring separation from contrib-specific tests.
