[tz] leap_second.list not updated after latest IERS Bulletin C

[Maximilian Linhoff]

Dear IANA Timezone People,

The latest leap_seconds.lst file you provide here:
https://data.iana.org/time-zones/tzdb/leap-seconds.list
and the other related files were last updated 2023-03-28.
The leap second table has an expiry date of 2023-12-28, which is
rapidly approaching.

There is IERS Bulletin C from 2023-07-04 announcing no new leap
second on 2023-12-31, so the expiry date of the list can be updated
to 2023-06-28.

Kind regards
Maximilian Linhoff
