chore(deps-dev): remove unused `@testing-library/` deps

[agilgur5]

Motivation

• they're not used in the repo -- can search the repo for @testing-library and get no results other than the dep manifests
  • I guess I missed these in my previous removals (#534) and assumed they were used or something
  • there aren't that many tests in this repo either
  • while testing-library is the preferred tool in the ecosystem these days, enzyme is still used in this repo
    • potentially could be replaced by testing-library (if no mounting etc is necessarily used), but not necessarily worthwhile given the deprecated state of this repo (#453)

Modifications

• remove @testing-library/ deps from the package.json and yarn.lock via yarn remove

• also automatically reorder the @types/uuid dep

  • happens automatically on a yarn add or yarn remove, I just left it out from previous removals as they were much larger and so it could be distracting

Verification

Build, lint, test, etc all still function fine as CI shows

Rebased it myself here and it's working for me locally. I'd guess your merge conflict resolution was not as precise as mine? I fixed the package.json and then git checkout --ours yarn.lock (to get the newest merged version) and then yarn to re-remove @testing-library/ and its deps
