Global Cordova v9 required due cocoapods management inconsistency

Defined minimal version of "cordova" package supported as version 9. Due to issues of supporting lower versions and "cordova-ios@5+" without deprecated configuration.

Removed explicit definition of "Firebase/Analytics" and "Firebase/Messaging" due to lack of matching “>=” definitions between plugins.

Special thanks for @DaedalusAB, for leaving a patch that led me to understand find the issue behind it.
