>> 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.

Suggestion:

            if (currentContainer instanceof KeyContainer kc
                && kc.getKey().equals("number")
                && attributes.getValue("sample").equals("-")) {

Similar to lines 813 to 817 above, the `&&` operator is placed in front to make the style consistent.
