feat(core): add Translation into demo with fetch locale from json file

[ghiscoding]

TODO

• Add a TranslationService which will use the Fetch API
• Add Translation into at least 1 demo page (Example 10)
• Slick Pagination has 2 texts "of" but only one get translated
• Possibly pass a Global Event Service instance (same as Aurelia) that could be passed by the Demo!?
  • or add an directly into the Translate Service that slick-vanilla-bundle can directly subscribe to
• add Unit Tests
• add Cypress E2E tests
