[ecash-agora] Minor version bump to reflect updated deps

Summary:
For apps and monorepos using ecash-lib and ecash-wallet and also ecash-agora, issues come up if they try to upgrade ecash-lib and ecash-wallet, because now ecash-agora is depending on the older versions. Bump here to keep everything consistent.

No expected change in behavior.

Test Plan: npm test
