Jade Lovelace 332bc64369 ci/eval: accept nix directly
Previously we were taking nixVersions and this made external use from
the Lix repo's CI annoying.

We should probably also test other nix versions than stable (i.e. also
latest and Lix), but this involves writing GitHub Actions about it and
maybe not running it on every single PR. Future work.

/**
Instantiate the library tests for a given Nix version.
IMPORTANT:
This is used by the github.com/NixOS/nix CI.
This is used by Lix's CI (see flake.nix in the Lix repo).
Try not to change the interface of this file, or if you need to, ping the
Nix AND Lix maintainers (`nix eval -f . lib.teams.lix`) for help. Thank you!
