Fixing TZDB build tool to accommodate full month/day names. Recently released tzdb2024b included (inadvertently) full month name "April", which is allowed by the spec (zic.8), but never used. This will cause build failure of the JDK. The proposed fix is manually tested by modifying the tzdb files to include full month names, and confirmed the successful build of the JDK.
