contrib/tzdata: correct DST in Fiji

Direct commit to stable/12.

Unfortunately, there is still no clear consensus on the tz mailing list
about some of the changes introduced by tzdata 2021b and later releases.
Pending consensus, only merge the recently announced DST transition date
for Fiji and corrections to commentary from tzdata 2021d.  This corrects
future timestamps in Fiji.

Approved by:	re (gjb)

+# Fiji, prime minister Josaia Voreqe "Frank" Bainimarama announced the
+# suspension of DST for the 2021/2022 season: "Given that we are in the process
+# of readjusting in the midst of so many changes, we will also put Daylight
+# Savings Time on hold for this year. It will also make the reopening of
+# scheduled commercial air service much smoother if we don't have to be
+# concerned shifting arrival and departure times, which may look like a simple
+# thing but requires some significant logistical adjustments domestically and
+# internationally."
+# Assume for now that DST will resume with the recent pre-2020 rules for the
+# 2022/2023 season.
