This was the testcontainer example from js-sdk

It builds and passes tests. Tests run via ts-jest; prepack runs the build script before pack or publish.

The output from npm pack or npm publish --dry-run is what I would expect (and hope for).

npm test
npm publish --dry-run

Still TODO:

1. GitHub actions to publish/release
2. Add to https://github.com/testcontainers/community-module-registry/blob/main/modules/dapr/index.md

This looks fantastic - thank you for putting the Dapr copyright header on all the files and for generally putting together a solid implementation.
