  [JSC] U+2212 MINUS SIGN should be rejected in ISO8601 strings
https://bugs.webkit.org/show_bug.cgi?id=278075

Reviewed by Ross Kirsling.

In the latest Temporal spec[1], the U+2212 MINUS SIGN cannot be used to represent negative numbers.
This is consistent with RFC3339[2] and RFC9557[3].

However, the current JSC allows the U+2212 MINUS SIGN within ISO8601 strings.

This patch changes to reject the U+2212 MINUS SIGN as the symbol for negative numbers in ISO8601
strings.
