Deprecations

@angular/build

• The baseHref option under i18n.locales and i18n.sourceLocale in angular.json is deprecated in favor of subPath.

The subPath defines the URL segment for the locale, serving as both the HTML base HREF and the directory name for output. By default, if not specified, subPath will use the locale code.
