TypeScript: changeTheme is not declared

[robertmorgan]

Describe the bug

If your project uses TypeScript, and you're following the guide on how to switch themes, then TypeScript will complain that:

Property 'changeTheme' does not exist on type '{ config: PrimeVueConfiguration; }'

The function exists in JavaScript, it's just not declared properly for TypeScript.

Another bug references this issue, however it's probably not getting the attention due to the bug report's title remaining as the template default.

Reproducer

https://codesandbox.io/s/objective-matsumoto-znzm79?file=/src/App.vue

PrimeVue version

3.29.2

Vue version

3.x

Language

TypeScript

Build / Runtime

Nuxt

Browser(s)

No response

Steps to reproduce the behavior

1. Follow the guide on how to switch themes from the PrimeVue site.
2. Ensure that your script block has the lang="ts" attribute so that it is using TypeScript
3. Observe the TS error in your IDE / run your TypeScript compatible build process to get the same error thrown.

Expected behavior

changeTheme should be present on the exported module signature for PrimeVue, alongside config.
