Updating shell.nix nightly

[gilescope]

The 2022-02-10 nightly can't build a dep we're pulling in:

There's a sig that returns impl IntoIterator<Item = (&'static str, OsString)> and an Option is being returned as the concrete implementation of the iterator but it's incorrectly not allowing a ? in the method.

Does not work for me…

A CI check would help to spot these regressions.

Good spot. That test is unlikely to pass on anyone else's machine than his. I don't think he intended to commit that version. I've removed it.

[ggwpez]

It somehow still fails… I will open a CI ticket, maybe we can get a check?

The CI check says its fine now, so should be good.
