Fix typos.

Also, the example of searchAnalyticsQuery() is not correct. The example has 5 parameters function expect 6.

    $data = SearchConsole::setAccessToken($token)->setQuotaUser('uniqueQuotaUserString')
        ->searchAnalyticsQuery(
            'https://www.example.com/',
            Period::create(Carbon::now()->subDays(30), Carbon::now()->subDays(2)),
            [['dimension' => 'query', 'operator' => 'notContains', 'expression' => 'cheesecake']],
            1000,
            'web'
        );
