(ios) fix: resolve correct path to app info plist when multiple plist…

… files are present (#144).

When multiple plist files exists in a cordova-ios project (e.g. due to a plugin containing `<podspec>`), ConfigFile was updated under CB-5989 to select the app plist as the target for changes destined for *-Info.plist.
However, the change made under CB-5989 incorrectly constructed the path to the app plist by omitting the project name subdirectory from the path, causing the fix to fail to work.

This commit fixes this by correcting the constructed path to the app plist.
