Why are these changes needed?
The "Train tests and examples" pipeline is being thinned out in scope of the storage API refactor. After #38759 was merged, one of the jobs doesn't contain any tests anymore. This is not correctly detected by the sharding script, so bazel complains about an empty test suite.
This PR reduces the parallelism of this job so that it's not empty anymore. This does not change any Ray code. (There's only a trivial change to trigger testing).
