I tried running the tests locally and they fail to execute because the npm test command uses the tap library to run the tests.

There are significant changes coming to the library following the upgrade to Cosmos SDK 47. We need to:

1. Wait for the new changes on akash-api for the latest protobuf types
2. Adapt the examples/tests to make them work with the latest changes
3. Make the examples/tests run on sandbox
