ALCHEMY_API_KEY=alchemykeygoeshere yarn test utils/ens-cache.test.js
```
Two notes on the test plan:
1. I originally wanted test cases for an ETH name that wasn't normalized and for a reverse resolution that didn't have a matching forward resolution, but I couldn't find anything in the wild. I found non-normalized ETH names but none of them had a reverse resolution set, and I didn't find any reverse resolutions without matching forward resolutions. I could construct these myself but it would probably require hitting some APIs directly or something, since I'm guessing ENS doesn't want you doing these things. Probably not worth it.
2. The tests require `ALCHEMY_API_KEY`, otherwise they are silently ignored. This diff adds that environmental to GitHub Actions, but the tests will get ignored when run in precommit hooks and in Buildkite. Discussing with Atul about potentially making it work on Buildkite, but my impression is that it might not be worth the time.
