Feature request: support different enum key

[liveMomentY]

What happens?

In backend generation tools, it is possible that the enum key are generated in the format of "x-enum-varnames".

What were you expecting to happen?

like "https://github.com/acacode/swagger-typescript-api"

getEnumNames = (schema) => {
  return (
    schema["x-enumNames"] ||
    schema["xEnumNames"] ||
    schema["x-enumnames"] ||
    schema["x-enum-varnames"]
  );
};

What versions are you using?

Package Version: 6.28.2
