Templates have not been upgraded for XCode 10

[landabaso]

For example, this file:

https://github.com/apache/cordova-ios/blob/master/bin/templates/project/__TEMP__.xcodeproj/project.pbxproj

still uses developmentRegion = English; (which is deprecated) instead of developmentRegion = en;

Compare it to:
https://github.com/dpogue/cordova-ios/blob/master/CordovaLib/CordovaLib.xcodeproj/project.pbxproj

They do not match. master fixes some of these inconsistencies (not all of them such as developmentRegion). What is worse, last release 5.1.1 targets compatibilityVersion = "Xcode 3.2";, which is pretty old.
See: https://github.com/apache/cordova-ios/blob/rel/5.1.1/bin/templates/project/__TEMP__.xcodeproj/project.pbxproj

There were many fixes applied in pull request #489 for CordovaLib.

But templates did not get those changes or got them partially wrong.

I'm not an expert in Cordova but I believe these templates are used to create the XCode project.

I found XCode was warning about a bunch of issues in my project which had been already solved for CordovaLib. I believe that the templates should have been upgraded accordingly.
