It appears that a lot of tooling does not support OpenAPI v3.1, so this changes
openapi-generatorto output OpenAPI v3 for broader compatibility. The largest change is with explicitnull-typed properties, since OpenAPI does not have anullprimitive type. As a workaround, I have it emit anullabletype with an emptyenum, which should mean the only possible value for that type isnull, but I'm guessing a lot of tooling conflates "nullable" with "optional" and we might need to handle this in the future.
