Expands and updates (following the normative change in https://github.com/tc39/proposal-temporal/pull/3107, approved May 2025) the current coverage with cases where the number of seconds is incorrect, or rounded. Adds missing coverage for sub-minute offsets in strings passed to Temporal.ZonedDateTime.compare. Adds the unusual test case of Pacific/Niue on October 15, 1952, where the offset shifted by 20 seconds to a whole-minute boundary. Fixes a few minor errors in the existing tests such as a missing ] in a string, and the wrong sign for the offset in Africa/Monrovia in property bags.
