Add support for Unicode properties `Script` values added in ES2022

Syntax name

List new Unicode v14 Script/Script_Extensions values

Syntax proposal URL

There are no proposals. These seem to have been added due to the Unicode v14 update.

https://github.com/tc39/ecma262/pull/2515

Example code

/* eslint no-invalid-regexp : ["error"] */

// False positives
new RegExp("\\p{Script=Cpmn}", "u");
new RegExp("\\p{Script=Cypro_Minoan}", "u");
new RegExp("\\p{Script=Old_Uyghur}", "u");
new RegExp("\\p{Script=Ougr}", "u");
new RegExp("\\p{Script=Tangsa}", "u");
new RegExp("\\p{Script=Tnsa}", "u");
new RegExp("\\p{Script=Toto}", "u");
new RegExp("\\p{Script=Vith}", "u");
new RegExp("\\p{Script=Vithkuqi}", "u");

Additional comments

I think that can be fixed by changing regexpp. https://github.com/mysticatea/regexpp/pull/27

ESLint has a false positive in the no-invalid-regexp rule. DEMO

I don’t have any particular knowledge or preference as to other packages to use.

@ota-meshi thanks! Marked as accepted. It seems we’re just waiting for regexpp.
