Type definition ZodFirstPartySchemaTypes is missing some first party schema types

[MatthijsMud]

While trying to create an object which maps from ZodFirstPartyTypeKind to a function that takes the associated schema as argument, I found that ZodReadonly and ZodSymbol are missing from ZodFirstPartySchemaTypes union. The basic premise of the mapping is as follows.

type ZodFirstPartySchemaForType<T extends ZodFirstPartyTypeKind> = ZodFirstPartySchemaTypes extends infer Schema 
  ? Schema extends { _def: { typeName: T} } 
    ? Schema 
    : never
  : never;
type ZodSchemaMap = { [key in ZodFirstPartyTypeKind]: ZodFirstPartySchemaForType<key> };

Based on this mapping we could then infer which types are missing:

type MissingSchemaTypes = { [key in keyof ZodSchemaMap as ZodSchemaMap[key] extends { _def: never } ? key : never ]: true }
