`UseOneOfForPolymorphism` puts `discriminator` in useless place in swagger-file

[SimonSimCity]

VERSION:

6.5.0

STEPS TO REPRODUCE:

Create an endpoint with an abstract class which is extended by two classes, whose instances could properly be returned at this endpoint. Enable UseOneOfForPolymorphism and set SelectDiscriminatorNameUsing and SelectDiscriminatorValueUsing.

EXPECTED RESULT:

As UseOneOfForPolymorphism replaces the usage of the abstract-class by a list of oneOf definition, containing the two classes extending it, the property discriminator should be on the oneOf definitions.

ACTUAL RESULT:

The property discriminator is instead defined on the component definition of the abstract class, where it's quite useless.
