Insert defaultValue is not typed if field is a nullable or optional array

[nianiam]

Describe the bug and the expected behavior

I am creating some dynamic fields in my form using the form.insert method, but noticed that I was getting a type error whilst trying to add some default values. It would appear that when the field is an array and is optional/nullable then the defaultValue type becomes a string. Here is a simplified example

export const schema = z.object({
  test: z.array(z.object({ nested: z.string() })).nullable() // or .optional()
})

<button
  {...form.insert.getButtonProps({
    name: fields.test.name,
    defaultValue: { // <-- Type '{ nested: string; }' is not assignable to type 'string'.
      nested: "I am nested",
    },
  })}
>
  Click me
</button>

It's fairly easy to work aroud this situation by making the field required and setting the default value of the form to an empty array, however, I thought I would report in case this was not deliberate!

Maintaining the type inside of the array would make the most sense.

Steps to Reproduce the Bug or Issue

@edmundhung this seems to be related to the defaultValue fix that @aaronadamsCA did whenever a schema has a key that is an array that also has an optional() or nullable() this seems to still have an issue.

Thanks for reporting the issue! This is fixed in v1.1.3.
