Multiple brands schema results to never

[zkulbeda]

Hi! Current implementation of branded types uses single symbol for single branded type, that results to never type in tests

valibot/library/src/methods/brand/brand.test.ts

Lines 32 to 38 in ce49b0b

	test('should allow multiple branding', () => {
	const branded1 = brand(string(), '1');
	const branded2 = brand(branded1, '2');
	type Branded2 = Output<typeof branded2>;
	expectTypeOf(branded1).not.toEqualTypeOf(branded2);
	expectTypeOf<Branded2>().toEqualTypeOf<string & Brand<'1'> & Brand<'2'>>();
	});

It happends because typescript resolves { [symbol]: "1"} & { [symbol]: "2" } to never.

I'll make a pr for fix, that replaces single value to object of values

Thank you! Can you also add a test that checks this?

@fabian-hiller sure!
