This fix pins the transformer and datasets module versions in hyperdisk example.

Can you point to the RCA on how pinning the dependency version succeeds the test. The test should not be dependent on a specific version of transformer as its not the core part of the blueprint to test.
Moreover cloud docs for running tensorflow examples are not pinning the dependencies.
