form.value should used combined type

[lifeiscontent]

Describe the bug and the expected behavior

I want to be able to reach into the form.value but it says I can't because its a union type, it'd be nice if I didn't have to type check the intent everywhere.

Conform version

latest

Steps to Reproduce the Bug or Issue

1. create a schema with a discriminated union
2. try to access the individual properties in typescript and watch it complain

What browsers are you seeing the problem on?
