ios: Remove deployment-target

[MaximBelov]

Reference

SDK-XXXX -- <TITLE>.

Summary

Motivation

Preference deployment-target should be defined in config.xml https://cordova.apache.org/docs/en/latest/config_ref/index.html

The value from the plugin overrides the value from config.xml

Value from config.xml should have more priority than value from the plugin

Please remove this preference and add it to the documentation. https://help.branch.io/developers-hub/docs/cordova-phonegap-ionic#configure-app

Bump on this, would like this merged as it's causing issues with cordova-plugin-firebasex pods.
