Jesse Alama 7d82f8ac63 Add tests for invalid extended year "-000000"
https://github.com/tc39/proposal-temporal/issues/1753 records the
consensus reached at the October 2021 TC39 meeting to disallow "-000000"
as an extended year, both in Date.parse and Temporal. This adds tests for
the Temporal part of that.
