@formatjs/intl-utils is deprecated

The package @formatjs/intl-utils is deprecated and should be replaced with @formatjs/ecma-abstract.

See also logs during npm install:

npm WARN deprecated @formatjs/intl-utils@3.8.4: the package is rather renamed to @formatjs/ecma-abstract with some changes in functionality (primarily selectUnit is removed and we don't plan to make any further changes to this package

Since custom-card-helpers is the only dependent module consuming @formatjs/intl-utils.
