Codegen typesPrefix not supported?

[ziimakc]

If I use typesPrefix codegen option to add prefix for generated types it doesn't apply to generated mercurius-js specific types.

For example:

declare module "mercurius" {
	interface IResolvers
		extends Resolvers<import("mercurius").MercuriusContext> {}
	interface MercuriusLoaders extends Loaders {}
}

Will point to Resolvers interface which is named GqlResolvers in generated file.

Is there a way to resolve this or does it needs to be fixed?
