[EarlGrey2] AppFramework does not build - 'GREYUILibUtils.h' file not found

[brocklyons]

It looks like the AppFramework does not build after this commit:
8a4af43

Repro steps:

1. Clone a fresh EarlGrey2 instance from the repo using the given steps:

// Clone EarlGrey 2.0
git clone -b earlgrey2 https://github.com/google/EarlGrey.git

// Download any dependencies
sh Scripts/download_deps.sh

2. Open the xcodeproj in Xcode 14 (also repros in Xcode 13)
3. Select "AppFramework" as the build target, kickoff build with 'Cmd + B'

The build immediately fails with: 'GREYUILibUtils.h' file not found

The previous commit does not run into this issue: 4e3e675

The file does exist in the repo, but the entire "Utils" directory where it lives is not shown in the Xcode project
