Remove permitted next node YAML - no longer needed
Remove permitted next node YAML - no longer needed

I ran the following command again:

    $ rails r script/generate-permitted-next-nodes-for-all-flows.rb

And the generated YAML was identical to the original version generated before
all the flows were changed to use the mechanism to automatically detect
permitted next nodes. So this file has served its purpose and can be removed.
