Update to 6.95

Upstream changes:
6.95  expected 2024-03-01
  -  Better support for weeks of the year
        Added the Week1ofYear config variable and deprecated the Jan1Week1
        variable. The first week of the year can now be specified much more
        easily.

  -  Support for the standard POSIX strftime directives in printf
        The Date::Manip::Date::printf method uses a set of directives which
        is similar, but not identical, to the POSIX strftime directives.

        A new config variable Use_POSIX_Printf has been added. If set, the
        printf method will use the POSIX strftime directives more fully
        (see the PRINTF DIRECTIVES section in the Date::Manip::Date POD for
        more information).

        Reported in GitHub #48

  -  Time zone fixes
        Newest zoneinfo data (tzdata 2024a).
