    [MINOR][DOC] Use `Java 8` instead of `Java 8+` as a running environment
    
    After Apache Spark 3.0.0 supports JDK11 officially, people will try JDK11 on old Spark releases (especially 2.4.4/2.3.4) in the same way because our document says `Java 8+`. We had better avoid that misleading situation.
    
    This PR aims to remove `+` from `Java 8+` in the documentation (master/2.4/2.3). Especially, 2.4.4 release and 2.3.4 release (cc kiszk )
    
    On master branch, we will add JDK11 after [SPARK-24417.](https://issues.apache.org/jira/browse/SPARK-24417)
    
    This is a documentation only change.
