In many cases we created a TimeZone or Calendar instance from a built-in
time zone or calendar. These tests can be trivially adapted to just use
the string ID.
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.
