New version of yiisoft/i18n package was released.
This version adds support for keywords hours, colnumeric, and colcasefirst. These keywords are part of the ECMAScript 2022 Internationalization API Specification (ECMA-402 9th Edition), and supporting them allows for better cross-communication between PHP and JavaScript layers.

• hours defines an hour cycle for the locale (i.e. h11, h12, h23, h24). For more information see the key/type definition for the Unicode Hour Cycle Identifier.
• colnumeric and colcasefirst are both collation settings defined as part of the Unicode Locale Data Markup Language.
