backport of #43786 to release/5.0
/cc @tqiu8
Customer Impact
In some cases the browser ends up using older names for timezones. This adds back backward compatibility to timezone data, allowing the browser to find local timezones even with outdated ids. Applicable to all Argentina timezones. Fixes #43518.
Testing
Missing test cases were added into TimeZoneInfoTests. 2 tests were added to address this issue.
Risk
Low, fix is very small and easy to understand.
