ArgumentError - [Xcodeproj] Unable to find compatibility version string for object version `70`.

I am receiving this error after updating my .pbxproj file using Xcode 16.0:

> ArgumentError - [Xcodeproj] Unable to find compatibility version string for object version `70`.

I'm using xcodeproj 1.27.0

I noticed this in `lib/xcodeproj/constants.rb`:

```
COMPATIBILITY_VERSION_BY_OBJECT_VERSION = {
77 => 'Xcode 16.0',
```

This doesn't seem right. I thought 70 is Xcode 16.0 and 77 is Xcode 16.1.

Any help would be appreciated.
