Title: [SPARK-3829] Make Spark logo image on the header of HistoryPage as a link to HistoryPage's page #1

There is a Spark logo on the header of HistoryPage.
We can have too many HistoryPages if we run 20+ applications. So I think, it's useful if the logo is as a link to the HistoryPage's page #1.
