Fix @return type, simple fixes

These are not changes that are not hooks and the issue that added the @return statement. Skimming those issue I did not see anything that suggests these should be returning a value.

\Drupal\Core\Config\ImmutableConfig::delete : added in #2392319: Config objects (but not config entities) should by default be immutable → . The return type added in first patch where it was like it is now, only throwing an exception.
\Drupal\rest\Routing\ResourceRoutes::onDynamicRouteEvent : #2158571: Routes added in RouteSubscribers cannot be altered → in #134.
\Drupal\locale\PluralFormula::loadFormulae : #2571375: Remove TranslationManager dependency from LanguageManager → in #19
TemporaryArrayObjectThrowingExceptions : #3232074: [Symfony 6] Add "array|string|int|float|bool|\ArrayObject|null" to all Normalizer classes that implement the method ::normalize() →

Add SqlContentEntityStorageSchema. The return type was added in #2183231-34: Make ContentEntityDatabaseStorage generate static database schemas for content entities → and was later committed. The function never had a return statement.

1) core/modules/rest/tests/src/Functional/ResourceTestBase.php

protected static function recursiveKSort(array &$array) {
    // First, sort the main array.
    ksort($array);

    // Then check for child arrays.
    foreach ($array as $key => &$value) {
      if (is_array($value)) {
        static::recursiveKSort($value);
      }
    }

    return $array;
  }

}

This function still returns an array and I think it will not be appropriate to remove the @return comment for this function until the function is updated to not return anything (As this function is updating a variable passed by reference this may be updated to not return anything in a separate issue and comment may be updated accordingly too).

@atul4drupal, thanks.

I reverted that change and created a new issue for ResourceTestBase, 📌 Fix return type in \Drupal\Tests\rest\Functional\ResourceTestBase::recursiveKSort Active

Seems there are some test failures.

Have not reviewed

The failures are unrelated. I rebased the MR via GitLab and tests are passing now. Therefore, I am restoring RTBC.

1) Drupal\FunctionalJavascriptTests\Ajax\ThrobberTest::testProgressThrobberPosition
Behat\Mink\Exception\ElementNotFoundException: Element matching xpath "//div[contains(@class, "dropbutton-wrapper")]/following-sibling::div[contains(@class, "ajax-progress-throbber")]" not found.

1) Drupal\Tests\toolbar\FunctionalJavascript\ToolbarActiveTrailTest::testToolbarActiveTrail with data set #1 ('horizontal')
Failed asserting that false is true.

I think the change to hook_theme_suggestions_alter() needs a bit more work while we are here, but otherwise I checked each case and they all look correct to me.

Adding tag.

There are no code changes and a followup has been made so I am restoring the RTBC.

Per #12

Thanks for opening the followup.
