Investigate removing lerna from this repo

[brownoxford]

This repo has only one package and Lerna is probably not required.

The issue here is that npm t is running lerna run test, and I'm not sure what lerna is doing here. I know that this is generating the context, and then checking the signatures for the credentials.

I added the following snippet to the CI. Not sure if this is calling the tests again, and the issue was that we weren't throwing errors for schemas not being correct.

      - name: Jest
        run: cd packages/traceability-schemas && npm run test

[brownoxford]

We are still using lerna in package.json to run linting and testing

@brownoxford , any change you'd dive into this still?
