@JsonUnwrapped required properties will not be copied when a prefix or suffix is used

[ondrejkrpec]

See:

• @JsonUnwrapped required properties will not be copied #3879
• Schema with @JsonUnwrapped does not include required properties springdoc/springdoc-openapi#1060

When a Type is annotated with @JsonUnwrapped and uses the attributes prefix or suffix then the required properties won't be mapped to the unwrapping Schema.

The fix linked above only fixes an option when both the suffix and prefix attributes are blank.
