ci: build sdk image for multi-chain test (#10880)

closes: #9805

## Description

Build the SDK Docker image so that the multi-chain test can use an up-to-date SDK image instead of the last published one.

### Security Considerations
None

### Scaling Considerations
This will make multichain tests in CI 5 minutes longer until we can amortize build through a shared step and depot runner, or some other explicit image sharing mechanism between pre-requisite jobs.

### Documentation Considerations
None

### Testing Considerations
Manually verify the integration test output of this PR

### Upgrade Considerations
None, testing only

+# Starship Devnet Action (Agoric fork)
+
+This `starship-action` was extracted from https://github.com/hyperweb-io/starship-action/tree/0.3.0
+
+We took:
+- action.yaml
+- install.sh
+- port-forward.sh
+
+Agoric added the `load-docker-images` input parameter to be able to import locally-built Docker images into Starship's Kubernetes cluster.
+
+Also, we ran `yarn prettier --write .github/actions/starship-action` to reformat
+the code to our repository's standards.
