[jdk17u] RFR: 8352097: (tz) zone.tab update missed in 2025a backport

[Andrew John Hughes]

As with [21u](https://github.com/openjdk/jdk21u/pull/460), the [17u backport](https://git.openjdk.org/jdk17u-dev/commit/06ea6d5c17899df8fd83d0b14983c7c1e88d9cde) of the tzdata 2025a update missed an update to zone.tab, as this was not present in the [25u commit](https://git.openjdk.org/jdk/commit/caa3c78f7837b1f561740184bd8f9cb671c467eb) on which it was originally based, due to its removal in [JDK-8166983](https://bugs.openjdk.org/browse/JDK-8166983). The change was in [the 24u commit](https://git.openjdk.org/jdk24u/commit/81252ef76899ad95197550a11c2786ccf3cf0cd2) which was applied later than the 21u one.

We should add this missing change to the existing 2025a update in 17.0.15 and consider backporting JDK-8166983 for 17.0.16 (now proposed for [24u](https://github.com/openjdk/jdk24u/pull/150)).

Backport from 21u is clean. Tests pass:
