[BEAM-12919] Removed IBM Streams from runner matrix

[pcoet]

This removes IBM Streams from the capability matrix. I think we can just remove all references from the yaml data file, and nothing will break. Everything looks right on my localhost.

LGTM technically:

I'm just wondering if we should clear this with IBM folks first. @pgerv12 it looks like you originally added IBM Streams to the capability matrix in 0d7a885. Are you ok with us removing it now since IBM Streams is deprecated?

[pgerv12]

@TheNeuralBit Yes, I approve. Unfortunately the IBM Streams product is near end-of-life and the Streaming Analytics service is being deprecated (which offered our Beam runner).

Ack, thanks for the quick response
