Augment module types

[chrisjansky]

Describe the feature

Hi,

I am attempting to extend the templateParams property of ReactiveHead to get type safety in nuxt:

useHead({
  foo: true, // <--- Works fine (see below)
  templateParams: {
    foo: true, // <--- I want to get IDE type checking here
  },
})

With a lot of guesswork, I got so far:

declare module "@unhead/vue/types" {
  interface ReactiveHead {
    foo: boolean // <--- This works
    templateParams: {
      foo: never // <--- This doesn’t work
    }
  }
}

The strange thing is the root foo property is correctly typed, but I can’t change the templateParams prop at all. I tried different combinations but I wonder if it’s possible at all as it’s typed as internal ResolvableProperties type.

Thank you for any pointers!
