Resolving Issue #13902

[emilymamcarz]

Hello,

This PR resolves #13902.

Description

This PR corrects the subtests documentation example, which currently uses .. code-block:: pytest and displays all u characters in green. This is misleading because the real test output includes both passing and failing subtests, and pytest's syntax highlighter cannot distinguish between them. As a result, the documentation incorrectly implies that all subtests passed.

Solution

Replaces .. code-block:: pytest with .. code-block:: console to disable pytest-specific highlighting. This updates the subtest output example to show a realistic mixture of subtest results (e.g., u u u u uF) without relying on color and ensures the documentation reflects actual pytest output, including multiple subtest results and the final test failure due to failed subtests.
