EAS cli unable to read bundle identifier and other environment variables in `.pbxproj` file

### Summary

In my bareworkflow app, I am trying to run `eas build --profile development`,
The build does not start at all on `expo.dev`, because of validation error below:

I get error with:
```
Could not read bundle identifier from Xcode project (target = myappname, build configuration = Release).
```
The reason is that value of app bundle identifier in the `.pbxproj` file is
```
PRODUCT_BUNDLE_IDENTIFIER = "$(EXPO_PUBLIC_APP_BUNDLE_ID)";
```
This is because we still rely on `react-native-config` related `.env` file which holds value for `EXPO_PUBLIC_APP_BUNDLE_ID`, before we fully adopt CNG/prebuild.

Note: I am not ignoring `.env` as part of `.easignore`.
