Extra required asterisk is shown on every Field Group horizontal tab

I opened a MR with a potential fix. Not sure this is it though, but I did see that Claro's details.html.twig template has the same check for the required variable.

Hey Dieter

I'm going to close this one out as we had several reportings and there was an issue opened in field group instead.

What issue? I looked before opening one here but couldn't find one.

Mentioned diff works fine for me with a Drupal 10.3.10 setup. Thanks for your work :)
