Hey! I see that this is your first PR. That is great! Welcome! Symfony has a contribution guide which I suggest you to read. In short:
Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change. When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor! I am going to sit back now and wait for the reviews. Cheers! Carsonbot |

The new TypeInfo component doesn't handle this situation correctly.
Found this after upgrading to 7.3, where the PropertyInfo now calls TypeInfo, given this docblock:
In 7.3 it will throw
Symfony\Component\TypeInfo\Exception\InvalidArgumentException: Cannot set "Symfony\Component\TypeInfo\Type\UnionType" as a "Symfony\Component\TypeInfo\Type\UnionType" part.exception.This PR makes sure that nullable union types are also merged, before being passed to a new UnionType
