chore: pin cypress-circleci-reporter in tests

[wdoconnell]

In recent CI runs, our Cypress docker build fails at the following line:

RUN yarn add cypress-circleci-reporter

The cause is a recent update to cypress-circleci-reporter that pulls in a new release of xmlbuilder2, which is incompatible with our Node configuration in CI. As this pertains to CI only, and should be obviated by a broader Cypress upgrade, the proposed solution here is to pin to the 0.3 version of cypress-circleci-reporter.
