Configure non-nullable types as required

Closes #2036

Seems like the build pipeline is broken but this should have nothing to do with my changes.

@blouflashdb there’s one more thing to consider: default values

public string Prop { get; init; } = "default value";

It’s non-nullable, yet it shoudn’t be required as it has a default value.

See how ASP validation is working as a result of this issue

You are right, I should take a look at the implementation in AspNetCore to match the behavior in Swashbuckle.

Hi, this feature would help a lot, especially with generating APIs from swagger documents :) Is there a way to help this move forward?
