oathkeeper: update judge/decisions endpoint in swagger docs for OS12

[spiri-bot]

Hi there,
the oathkeeper docs for OS12 reflect the current state of 0.16, but the swagger api docs still state the /judge instead of the new /decision endpoint. This took me a bit to realize, since it is only mentioned in the upgrade docs, so maybe this should be updated :)
If you point out docs or recipe on how to regenerate, I'd be happy to do this myself.
Cheers and thanks for the great tool!
