@desktop/engineering not sure if the only running CircleCI is due to a PR targeting port-integration-tests-to-jest vs development branch but just wanted to call it out.

@say25 I started bashing my head against these tests once I realised the issue yesterday, but NYE meant I didn't update the PR to add this context.

Thinking on this some more, we can do this transition without continuing to stack pull requests:

• I'll update port integration tests to jest #6518 to not remove the mocha and chai packages (should make the build green again)
• You can open a fresh PR targeting development (rather than targeting port integration tests to jest #6518) to tidy up the remaining chai usages in the unit tests

Once both those are in, we can remove the packages from package.json.

@say25 thanks for helping migrate these over!
