Export enums as const too, like Prisma

Hi! Awesome work on this library, thanks for the time and effort!

When switching over from everything Prisma to Kysely, and generating the types with this library, I noticed the enums are not exported like Prisma does. The enum types are only exported as a type, and not include a const export like Prisma does.

So, for example if I have this defined in my schema.prisma:

enum Language {
  NL
  EN
}

Prisma generated:

export const Language: {
  NL: 'NL',
  EN: 'EN',
};

export type Language = (typeof Language)[keyof typeof Language];

Which I could then use in some zod validation schema:

const schema = z.object({
  language: z.nativeEnum(Language),
});

However, prisma-kysely only generates the type, which I cannot use in zod anymore:

export type Language = 'NL' | 'EN';

So I was wondering if we could have a similar export of enums when using prisma-kysely?

For now i'm using the exports from @prisma/client, but I would like to ditch that and use all the types generated by prisma-kysely.

Oh I hadn't thought of the zod use case. That sounds interesting. I'll give implementation a shot!
