Cole Helbling 64a8cc193d 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.

update-flake-lock

This is a GitHub Action that will update your flake.lock file whenever it is run.

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.

Example

An example GitHub Action workflow using this action would look like the following:

name: update-flake-lock
on:
  workflow_dispatch: # allows manual triggering
  schedule:
    - cron: '0 0 * * *' # runs daily at 00:00

jobs:
  lockfile:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v2
      - name: Install Nix
        uses: cachix/install-nix-action@v14
        with:
          install_url: https://nixos-nix-install-tests.cachix.org/serve/vij683ly7sl95nnhb67bdjjfabclr85m/install
          install_options: '--tarball-url-prefix https://nixos-nix-install-tests.cachix.org/serve'
          extra_nix_config: |
            experimental-features = nix-command flakes
            access-tokens = github.com=${{ secrets.GITHUB_TOKEN }}            
      - name: Update flake.lock
        uses: DeterminateSystems/update-flake-lock@v3
