chore: add reference nix package and flake

[acuteaura]

Type of change:

• [x] CI/CD or Tests

What this PR does / why we need it:

Allows for use in the Nix/NixOS ecosystem, for instance when building a custom container image.

Remarks

I left "build OS" set to unknown, since this piece of information is not easily exposed and should be irrelevant.

Updating

I'm happy to keep this in sync with current versions, but the process for updating the package is as follows:

1. Update "version" and "rev".
2. Set hash and vendorHash to lib.fakeSha256
3. nix build
4. Grab the hashes from error messages and place them where appropriate until the build succeeds.
