Compability with Angular Ivy

[grzegorzbernat]

The same error as here

    ERROR in node_modules/@ngsm/i18n/lib/i18n.module.d.ts:4:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.
    
    This likely means that the library (@ngsm/i18n) which declares I18nModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if s
o. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
