RewardedInterstitialAd events are not called on the main Unity thread

[ghost]

[REQUIRED] Step 1: Describe your environment

• Unity version: 2021.3.16f1
• Google Mobile Ads Unity plugin version: 7.4.1
• Platform: Android
• Platform OS version: Target: API 33
• Any specific devices issue occurs on: Tested on different devices with different Android versions
• Mediation ad networks used, and their versions:

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

Rewarded interstitial ad events do not occur on the main Unity thread, despite setting "MobileAds.RaiseAdEventsOnUnityMainThread" to true. Depending on what actions are taken in this event call-back, this may result in the application crashing.

This problem was already mentioned in the issue https://github.com/googleads/googleads-mobile-unity/issues/2676

Relevant Code:

As you can see here: https://github.com/googleads/googleads-mobile-unity/blob/v8.2.0/source/plugin/Assets/GoogleMobileAds/Api/RewardedInterstitialAd.cs

The events are still called via

_client.OnAdClicked += () => { if (OnAdClicked != null) { OnAdClicked(); } };

but should be called via

_client.OnAdClicked += () => { MobileAds.RaiseAction(() => { if (OnAdClicked != null) { OnAdClicked (); } }); };
