Philip Chimento 5c9ff876dc Temporal: Add test coverage for sub-minute UTC offsets in strings
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.
