e2e tests (#16533)

In this PR, 
- current basic E2E tests are fixed, and some were added, covering some
basic scenarios
- some tests avec been commented out, until we decide whether they are
worth fixing

The next steps are
- evaluate the flakiness of the tests. Once they've proved not to be
flaky, we should add more tests + re-write the current ones not using
aria-label (cf @lucasbordeau indication).
- We will add them back to the development flow
