`cachix` not found, breaking install step of action

[andyleejordan]

Hey @purcell, sadly an issue seems to have cropped up today. Not sure if it's a Nix update or a GitHub Action image runner update, but the install step fails because cachix isn't found:

2023-02-28T22:12:37.3188943Z manager. This will happen in a few stages:
2023-02-28T22:12:37.3189181Z 
2023-02-28T22:12:37.3189531Z 1. Make sure your computer doesn't already have Nix. If it does, I
2023-02-28T22:12:37.3189980Z    will show you instructions on how to clean up your old install.
2023-02-28T22:12:37.3190231Z 
2023-02-28T22:12:37.3190488Z 2. Show you what I am going to install and where. Then I will ask
2023-02-28T22:12:37.3190846Z    if you are ready to continue.
2023-02-28T22:12:37.3191062Z 
2023-02-28T22:12:37.3191333Z 3. Create the system users and groups that the Nix daemon uses to run
2023-02-28T22:12:37.3191668Z    builds.
2023-02-28T22:12:37.3191855Z 
2023-02-28T22:12:37.3192106Z 4. Perform the basic installation of the Nix files daemon.
2023-02-28T22:12:37.3192356Z 
2023-02-28T22:12:37.3192626Z 5. Configure your shell to import special Nix Profile files, so you
2023-02-28T22:12:37.3192972Z    can use Nix.
2023-02-28T22:12:37.3193153Z 
2023-02-28T22:12:37.3193331Z 6. Start the Nix daemon.

[akirak]

This seems to be an upstream issue. cachix/cachix-action fails to run, so I have filed a ticket: cachix/cachix-action#137

[pkryger]

Perhaps pinning nix will work as per cachix/cachix-action#138 (comment)?

[purcell]

On it, thanks.

[purcell]

Fixed by #34, thanks.
