Attempt to fix 1.82 CI

[Manishearth]

ICU4X 2.1 has MSRV 1.83

I hoped to get it work with the version-aware resolver, but that doesn't work, the config key is ignored for some reason. Going to fix it the other way.

(We can't globally enable it since we test on MSRV 1.63 which doesn't have the resolver)

@hsivonen looks like this fails IdnaTest with latest ICU4X

Seems to be resolved by updating IdnaTestV2

Why are all of the CI tasks immediately getting canceled when one fails? It's making it hard to fix these CI errors since a different one fails with a new one each time: i can never tell if what I am trying is working.

fail-fast is not set to true, so I'm not sure what's wrong
