Remove automatic Nix installation
There is currently no (easy) way to only enable a certain composite action step when some input is set, so just don't automatically install Nix at all.

This is a GitHub Action that will update your flake.lock file whenever it is run.
|
||||
|
||||
> NOTE: We hardcode the `install_url` to a relatively recent `nixUnstable` (`nix-2.5pre20211015_130284b` currently). If you need a newer version that includes a new feature or important bug fix, feel free to file an issue or send a PR bumping the `install_url` inside the [`action.yml`](action.yml)!
|
||||
> **NOTE:** As of v3, this action will no longer automatically install Nix to the action runner. You **MUST** set up a Nix with flakes support enabled prior to running this action, or your workflow will not function as expected.
