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

[gnu-andrew]

As with openjdk/jdk21u#460, openjdk/jdk17u#405 & openjdk/jdk11u#101, the 8u 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 8u452 and consider backporting JDK-8166983 for 8u462 (now proposed for 24 in openjdk/jdk24u#150).

Patch from 11u applies cleanly to the make/data file when applied from the jdk subdirectory (-p1) and to the copy in test/sun/util/calendar/zi/tzdata applied from test/sun/util/calendar/zi subdirectory (-p3) .

Testing showed no regressions:

$ for suite in jdk_time jdk_text jdk_util_other; do make -C $HOME/builder/8u test TEST="${suite}"; done 2>&1 | tee ${TMPDIR}/test.log
...
$ cat ${TMPDIR}/test.log|grep '^TEST'
TEST STATS: name=jdk_time  run=170  pass=170  fail=0
TEST: java/text/BreakIterator/BreakIteratorTest.java
TEST JDK: /home/andrew/builder/8u/images/j2sdk-image
TEST RESULT: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: Uncaught exception thrown in test method TestJapaneseLineBreak
TEST STATS: name=jdk_text  run=152  pass=151  fail=1
TEST STATS: name=jdk_util_other  run=351  pass=351  fail=0
