Add an isolated functional testing mechanism

Overview of the feature request

Add a functional testing mechanism for the use cases of the package that helps in the review and QA process of the PRs, so that the use cases can be tested in isolation, without having to depend on other repositories like the dataverse-frontend to prove that the use cases consumption works from a functional perspective.

These tests would help to verify that use cases can be imported with no issues, as stated in this comment: https://github.com/IQSS/dataverse-client-javascript/pull/116#issuecomment-1907711330

Commencez par examiner les cas d’utilisation du package et le commentaire lié de la pull request concernant leur importation sans problème.

La tâche est terminée lorsque les cas d’utilisation peuvent être testés fonctionnellement pendant la revue de la pull request et la QA.
