Implement Cypress for central dashboard

[mathis-marcotte]

Central Dashboard currently does have something for e2e testing. It is made with Jasmine. But, when trying to run the test suite made with it, I can't seem to get it to work. Plus, the only test case that seems to be implemented is for the registration page, which is not a feature we currently have.

I think this is a good time for us to replace the jasmine implementation with a Cypress implementation for e2e tests to match how they are done in Jupyter-apis.

I installed cypress for central dashboard and also implemented 1 test to just have something there. Nothing big, it just tests that we can hit kubeflow.
We can add extra tests, and also integrate cypress in our github workflow actions as next steps.
