Bumped CHaP index-state to pull in revision 1 of cardano-api 11.7, which bumps Plutus from 1.65 to 1.70

Wait, I see this branch depends on cardano-api-11.6, so I guess I should make a revision to 11.6 instead? @koslambrou @lehins

@zliu41 This PR targets the 11.1.x release branch. Is the Plutus bump necessary for node 11.1? You probably want to bump Plutus in master?

I guess I should make a revision to 11.6 instead?

@zliu41 Correct 👍
