test(quantic): adapted Quantic E2E for case assit with the new event protocol (#3754)

## [SFINT-5400](https://coveord.atlassian.net/browse/SFINT-5400)

- Adapted the Cypress e2e test for Case Classification and Document
Suggestion features for testing with analytics sent with the new
protocol, now the test spec tests for both cases: the case when send
legacy analytics and the case where we sent next analytics.

- In a nutshell that's what I'm doing in this PR:
wherever we were testing analytics like this:
```
Expect.logClickingSuggestion(clickIndex, allDocuments);
```
now we are testing it like this:
```
if (analyticsMode === "next") {
  NextAnalyticsExpectations.emitCaseAssistDocumentSuggestionClick(
    {
      documentSuggestion: {
        id: allDocuments[clickIndex].uniqueId,
        responseId: exampleResponseId,
      },
    },
    exampleTrackingId
  );
} else {
  Expect.logClickingSuggestion(clickIndex, allDocuments);
}

```
