An alt tag was added to the custom logo via this task: https://www.drupal.org/project/gin/issues/3293366 → , which will allow the code to pass automated tests. However, the alt tag is fixed as 'Home'. We recently had some accessibility testing carried out and this failed because the alt tag does not describe the image.
Inspect the code on the toolbar logo to view the alt tag.
Provide a text field in the theme settings where an alt tag can be added.

I'm closing this as we're using Core's logo field which does not provide an alt text. Please instead open an core issue for this, thanks!
