fix: make oneOf discriminator props required

[Liooo]

Closes #1561

Fix for the issue that discriminator.propertyName becomes optional in generated type.

https://github.com/OAI/OpenAPI-Specification/blob/3.0.3/versions/3.0.3.md#discriminator-object

The expectation now is that a property with name petType MUST be present in the response payload

Seems this should be always the case according to the spec too (same for 3.1.0).

Any idea why only 3.0.x snapshots are affected? You touched the 3.1.x parser too, so I'd expect those to be updated too. Perhaps different parts of the code were altered?

EDIT: I see it's because you touched the allOf function instead of oneOf in 3.1.x. I'll fix it

@mrlubos ops, thanks for that!
