I extended the existing test case to include the following steps:

1. Create an Ansible variable with a default value and an overridden key.
2. Update the value of the Ansible variable at the host level.
3. After updating, delete the value, ensuring that it reverts to the default value

Added to the entities with their respective locators:

• read_update_value: Reads the value after updating the Ansible variable in the host.
• read_delete_value: Deletes the updated value, reverts to the default value, and reads the default value.
