David Roberts 3f210e2620 [ML] Load data streams plugin for ML internal cluster tests (#63560)
Now that deprecation logs get indexed to a data stream, if we
do not load the data stream plugin in our tests and any test
generates a deprecation log message then millions of exceptions
get logged, slowing down the tests to the extent that they can
fail.

This change loads the data streams plugin during the ML internal
cluster tests.  (It should already be present in external cluster
tests.)

Fixes #63548
