feat: enhance CI/CD pipeline with unit and e2e testing

Introduce a new GitHub Actions workflow for running unit tests. The
workflow is triggered on every push to the main branch. It sets up a
Node.js environment, installs dependencies, and runs the unit tests.

In addition, the deployment workflow now depends on the successful
completion of both the unit testing and Playwright end-to-end testing
workflows. This ensures that the code is thoroughly tested before it
is deployed.

Finally, the semantic release workflow has been updated to depend on
the successful completion of the deployment workflow. This ensures
that a new release is only created after the tested and deployed code
is in production.
