@react-native-firebase/app and @react-native-firebase/admob pod install error

[tburnt]

Issue

I tried upgrading the library of react-native-firebase/app and react-native-firebase admob to 12.9.3 and 11.5 and then
pod install however the installation does not proceed and has this error

[!] CocoaPods could not find compatible versions for pod "Google-Mobile-Ads-SDK":
In Podfile:
Google-Mobile-Ads-SDK (= 8.8.0)

RNFBAdMob (from `../node_modules/@react-native-firebase/admob`) was resolved to 7.6.8, which depends on
  Firebase/AdMob (~> 6.30.0) was resolved to 6.30.0, which depends on
    Google-Mobile-Ads-SDK (~> 7.50)

Specs satisfying the Google-Mobile-Ads-SDK (= 8.8.0), Google-Mobile-Ads-SDK (~> 7.50) dependency were found, but they required a higher minimum deployment target.

Enables Flipper.

Note that if you have use_frameworks! enabled, Flipper will not work and

you should disable the next line.

AdMob is no longer a part of firebase upstream, and thus was removed here - still working on bringing up the code in a separate repository --> #5329
