[8.1] Add functional test for assertBrowserHistoryIsNotOnLastPage

[TavoNiievez]

Adds the one missing functional test for the Symfony-inherited browser-history assertions introduced in Codeception/module-symfony#240 (assertBrowserHistoryIsNotOnLastPage). The sibling assertions (IsNotOnFirstPage, IsOnFirstPage, IsOnLastPage) were already covered by #45–#48; this one was omitted because no public step could position the browser history off the last page.

public function assertBrowserHistoryIsNotOnLastPage(FunctionalTester $I)
{
    $I->amOnPage('/');
    $I->amOnPage('/login');
    $I->moveBack();
    $I->assertBrowserHistoryIsNotOnLastPage();
}

The assertion requires symfony/browser-kit >= 7.4, so it applies to the 7.4 and 8.1 branches only.

Depends on Codeception/lib-innerbrowser#87

On released lib-innerbrowser, moveBack() replays the previous request with changeHistory = true, which re-appends to the history and leaves the pointer on the last page — so this test only passes once Codeception/lib-innerbrowser#87 (move the history pointer instead of appending) is merged and released. CI here will be red until then.
