PR Summary

This pull request addresses a bug in the validmind/tests/load.py file where the iteration over test objects was incorrectly implemented. The iteration was previously done directly over the result of _load_tests(list_tests(pretty=False)), which is now corrected to iterate over the values of the dictionary returned by this function. This change ensures that the code correctly accesses the test objects and their associated attributes such as __tags__ and __tasks__.

The affected functions are:

• list_tags(): Collects unique tags from test objects.
• list_tasks_and_tags(): Maps tasks to their associated tags.
• list_tasks(): Collects unique tasks from test objects.

These changes improve the accuracy of the data collected by these functions.

Note: The version number in pyproject.toml and validmind/__version__.py was incremented from 2.6.7 to 2.6.8, but this is not functionally relevant to the changes in the code logic.

Test Suggestions

• Verify that list_tags() returns the correct set of unique tags from the test objects.
• Ensure list_tasks_and_tags() correctly maps tasks to their associated tags.
• Check that list_tasks() returns the correct set of unique tasks from the test objects.
• Test with a variety of test objects to ensure that the iteration over values works as expected.
• Run existing test suites to confirm no regressions are introduced.

If this is something the "explore tests" notebook would have made evident then let's add that notebook to the integration tests GH action.

It would have @cachafla... Adding that in my PR to main.
