Fix the failing RefApp 2.x Clinical Visit Test

The RefApp 2.x Clinical Visit Test workflow is currently failing. Specifically, it fails when attempting to save a visit note in the Complete visit note user story. The issue lies in the code, which currently uses an incorrect HTML element for the assertion.

We can fix this by updating the assertion.
/qaframework-bdd- tests/src/test/java/org/openmrs/contrib/qaframework/automation/ClinicalVisitSteps.java:systemAddsVisitNote() to:

@Then("the system adds the note into visit note table")
public void systemAddsVisitNote() {
    assertEquals(DIAGNOSIS_PRIMARY, visitNotePage.savedPrimaryDiagnosis());
}
