UMA-1876 cryptowatch api no longer works, causing CI to fail

see these examples: [https://app.circleci.com/pipelines/github/UMAprotocol/protocol/22127/workflows/ba05f1e7-d553-4ab9-90f9-b553da1d276c/jobs/197948](https://app.circleci.com/pipelines/github/UMAprotocol/protocol/22127/workflows/ba05f1e7-d553-4ab9-90f9-b553da1d276c/jobs/197948) [https://app.circleci.com/pipelines/github/UMAprotocol/protocol/22127/workflows/ba05f1e7-d553-4ab9-90f9-b553da1d276c/jobs/197942](https://app.circleci.com/pipelines/github/UMAprotocol/protocol/22127/workflows/ba05f1e7-d553-4ab9-90f9-b553da1d276c/jobs/197942) it looks like some tests we have depend on cryptowatch, which is no longer running. we will need to disable these
