fix: canSubmit with valibot variant schema

[Pascalmh]

I have a issue with onMount validation when using a v.variant Schema

The thing is that this is valid:

const values = useStore(form.store, (state) => state.values);
console.log('values', v.safeParse(ValibotSchema, values)); // { success: true, … }

While form.canSubmit remains false

• Open the Stackblitz https://stackblitz.com/edit/tanstack-form-cjr4wwda?file=src%2Findex.tsx
• Open Devtools/Console
• Select the "Cat"-Radio Button

Observe: canSubmit remains false.

• Select the "Dog"-Radio Button
• Give the Dog a cool name
• Select the "Cat"-Radio Button

Observe: canSubmit is true
