Add possibility to provide schema using Promises

[ShockOfficial]

Hi!
Something that really bothers me is that there is no way to provide schema asynchronously.
In the project, I am using next-intl with zod to give error messages in the appropriate language so basically the way to do that is to provide the translation function while creating the schema

export const createAddSpaceSchema = (
	t: TranslationFunction<'AddSpaceModalValidation'>,
) =>
	z.object({
		name: z
			.string()
			.min(3, { message: t('name_min') })
			.max(64, { message: t('name_max') }),
		description: z.string().min(1, { message: t('description_required') }),
		type: z.enum(['public', 'private']),
		tags: z.array(z.object({ value: z.string() })),
	});

On the server side, there is async getTranslations() function that can be used to get translations but the schema() can't handle Promises.

export const createSpace = action
	.schema(async () => {
		const t = await getTranslations('AddSpaceModalValidation');
		return createAddSpaceSchema(t);
	})
	.action(async (data) => {
		console.log('data', data);
		return {
			id: 1,
			name: 'test',
		};
	});

Something that I would appreciate is to have an interface for schema that accepts and handles Promise or other way to provide schema later on using maybe middleware with use and passing schema through ctx that would be typesafe

My current approach works but is not ideal since this is not type-safe on the client side.

export const createSpace = action
	.use(async ({ next, ...rest }) => {
		const t = await getTranslations('AddSpaceModalValidation');
		const schema = createAddSpaceSchema(t);
		console.log('rest.clientInput', rest.clientInput);
		const parsedData = schema.parse(rest.clientInput);
		return next({ ...rest, ctx: { schema, parsedData } });
	})
	.action(async (data) => {
		const { parsedData } = data.ctx;

		console.log('parsedData', parsedData);

		return {
			id: 1,
			...parsedData,
		};
	});

If there is no quick fix let me know. Will try to refactor the way I create schema with translations.
