document is incorrect.
## What changes were proposed in this pull request?
In `programming-guide.md`, the url which links to `AccumulatorV2` says `api/scala/index.html#org.apache.spark.AccumulatorV2` but `api/scala/index.html#org.apache.spark.util.AccumulatorV2` is correct.
## How was this patch tested?
manual test.

While this code used the built-in support for accumulators of type Long, programmers can also
-create their own types by subclassing [AccumulatorV2](api/scala/index.html#org.apache.spark.AccumulatorV2).

The AccumulatorV2 abstract class has several methods which need to override:
`reset` for resetting the accumulator to zero, and `add` for add anothor value into the accumulator, `merge` for merging another same-type accumulator into this one. Other methods need to override can refer to scala API document. For example, supposing we had a `MyVector` class
representing mathematical vectors, we could write:
