Tests for Temporal PR #2574

Edits Temporal tests to account for changes in
https://github.com/tc39/proposal-temporal/pull/2574.

This PR stops coercing non-string primitive inputs to strings
in Temporal methods, to avoid cases where numbers
are coerced to syntactically valid but often unexpected
string results.
