<i18n dev> RFR: 8363972: Loose matching of dash/minusSign in number parsing [v10]

[Naoto Sato]

> Enabling lenient minus sign matching when parsing numbers. In some locales, e.g. Finnish, the default minus sign is the Unicode "Minus Sign" (U+2212), which is not the "Hyphen Minus" (U+002D) that users type in from keyboard. Thus the parsing of user input numbers may fail. This change utilizes CLDR's `parseLenient` element for minus signs and loosely matches them with the hyphen-minus so that user input numbers can parse. As this is a behavioral change, a corresponding CSR has been drafted.
