The expiry date for the hardcoded leapseconds list should be updated
too, as there's a new date in the file in the tzdata distro. There are
no new leap seconds though, just a new "this list is valid until ..."
date.

Tested x86_64-linux and aarch64-linux.

    libstdc++: Update tzdata to 2023d
    
    Import the new 2023d tzdata.zi file. The leapseconds file was also
    updated to have a new expiry (no new leap seconds were added).
    
    libstdc++-v3/ChangeLog:
    
            * src/c++20/tzdata.zi: Import new file from 2023d release.
            * src/c++20/tzdb.cc (tzdb_list::_Node::_S_read_leap_seconds)
            Update expiry date for leap seconds list.
