v-ripple crash with vue 3.2.32+ with composition API

[NGPixel]

What happened?

Using vue 3.2.32 or later and the vue composition API (<script setup>), adding v-ripple to an element such as q-item results in a crash with error TypeError: Cannot read properties of undefined (reading 'config')

The workaround, as found by @Trinovantes (#13154 (comment)), is to expose $q via defineExpose() in any component where v-ripple is used:

<script setup>
import { useQuasar } from 'quasar'

const $q = useQuasar()
defineExpose({ $q })

The components that accept v-ripple should be modified to automatically expose $q so that we don't have to use this workaround.

⚠️🛑 This issue was originally discussed in #13154 but was closed since the specific issue from the original post was fixed, but not v-ripple, hence this new issue. 🛑 ⚠️

What did you expect to happen?

v-ripple should work without the workaround detailed above.

Adding a ? in front of $q in quasar/src/directives/Ripple.js fixes it for me:

1. Once again, just to be clear, this is due to a bug introduced in Vue 3.2.32.
2. Guarding the instance.$q is not an option as it means that in some scenarios (like this one), Ripple won't work as advertised (it will not keep into account the global config for it).

Pushed a workaround in Quasar for this issue since the fix in Vue takes longer than expected.
Fix will be available in Quasar v2.7.3
