Review comment:
I've filed https://issues.apache.org/jira/browse/BEAM-6679 to look at fixing
up `@literal` in other classes.

> [The current Javadoc for
> GroupIntoBatches|https://beam.apache.org/releases/javadoc/2.10.0/org/apache/beam/sdk/transforms/GroupIntoBatches.html]
> is strangely formatted, making it difficult to understand the code example
> and learn how to use the transform.
> The code example should also follow conventions from classes like MapElements
> where the code example assumes a PCollection of some type and demonstrates
> the output PCollection type after applying the transform.
