CON-1657 | Add selenium test for GameStar logo

You could move the assertion and logic into the GameStarLinkDisplay in the VenusGlobalNavPageObject method then call the method from the test class.
```
public void verifyGameStarLinkIsNotDisplay() {
  Assertion.assertFalse(gameStarLink.isDisplayed(), "GameStar Logo shouldn't be visible");
}
```
