types(ref): fix type error when ref parameter is of type any

[Alfred-Skyblue]

export function ref<T extends Ref>(value: T): T

This function overload matches the any type, and it returns any instead of Ref<any>.

const msg: any = 'hello'

const msgRef = ref(msg) // ===> any

// Expected `Ref<any>` for msgRef, but received type `any`.

In this PR, the function overload was removed because its outcome is identical to export function ref<T>(value: T): Ref<UnwrapRef<T>>.
