Update deps (ietf-tools#4203)

* chore: Update deps

There are these yarn messages, which I don't understand, but @NGPixel may.

```
➤ YN0000: ┌ Resolution step

```

* Use .yarnrc.yml from @NGPixel

* Fix tests.

I have no idea why they started failing, the both the js code and the tests have
not changed in months...
