8352097: (tz) zone.tab update missed in 2025a backport

[gnu-andrew]

As with openjdk/jdk21u#460 & openjdk/jdk17u#405, the 11u backport of the tzdata 2025a update missed an update to zone.tab, as this was not present in the 25u commit on which it was originally based, due to its removal in JDK-8166983. The change was in the 24u commit which was applied later than the 21u one.

We should add this missing change to the existing 2025a update in 11.0.27 and consider backporting JDK-8166983 for 11.0.28 (now proposed for 24 in openjdk/jdk24u#150).

Backport from 17u is clean. Tests pass:
