here we have a test which now returns a explicit NeverType. all other tests where adjusted to compensate the additional implicit information in the description. no changes regarding the typtes itself.

inspired by #2110 where we addd logic based on NeverType explicitness, I figured it would be helpful if the TypeCombinator would keep the exlicitness, instead of create a new non-explicit NeverType every-time it combines NeverTypes'.
Before this PR there was no way to differentiate between NeverType explicit and implicit - I therefore added the same "hack" we use to differentiate explicit and implicit MixedType in tests.
this could be followed up by changes in e.g.
phpstan-src/src/Reflection/InitializerExprTypeResolver.php
