function StableBaseThemeUpdateTest::testUpdateHookN

Tests that the Stable base theme is installed if necessary.

@expectedDeprecation There is no `base theme` property specified in the test_stable.info.yml file. The optionality of the `base theme` property is deprecated in drupal:8.8.0 and is removed from drupal:9.0.0. All Drupal 8 themes must add `base theme: stable` to their *.info.yml file for them to continue to work as-is in future versions of Drupal. Drupal 9 requires the `base theme` property to be specified. See https://www.drupal.org/node/3066038
