Incorporate Drupal 9.4 core changes to getLanguageSwitchLinks

Looking at https://git.drupalcode.org/project/dropdown_language/-/merge_requests/3/... I see the same fix as the one I just provided in 🐛 Warning: Attempt to read property "links" on null Closed: duplicate ( https://www.drupal.org/files/issues/2023-03-16/attempt-to-read-property-... → )

The only difference is the local variable name: my $language_switch_links vs languageSwitchLinksObject.
Up to the maintainer which version he wants. I'd say pick one and credit us both. :-)

The title of this issue really is outdated, though. And not helpful. :-)

Thanks @Eric_A. I agree and will do so! Just became maintainer. Let's fix all these issues around the NULL ;)

Fixed. I'll tag a 3.1.3 release now to get the WSODs away first!

@SKAUGHT, I'm missing the permission to administer releases. So I can't release 3.1.1 - could you add that permission please? (also sent you a PM).

Meanwhile cherry-picked into 4.0.x!

Fixing the title according to #2940121: ConfigurableLanguageManager::getLanguageSwitchLinks() doesn't respect what LanguageManagerInterface::getLanguageSwitchLinks() says to return →
