feat(nuxt): Add Sentry Pinia plugin (#14047)

closes #14039

By adding `trackPinia`, the Pinia store is monitored with Sentry.

```js
Sentry.init({
  dsn: useRuntimeConfig().public.sentry.dsn,
  trackPinia: true
});
```
or with custom options:
```js
Sentry.init({
  dsn: useRuntimeConfig().public.sentry.dsn,
  trackPinia: {
    actionTransformer: action => `Transformed: ${action}`,
  },
});
```
