Why julia-actions/add-julia-registry@v1 comes before julia-actions/setup-julia@v1 action in readme example?

[sairus7]

Shouldn't julia-actions/setup-julia@v1 always be the first julia-related action?

Code from readme.md:

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: julia-actions/add-julia-registry@v1 
        with:
          key: ${{ secrets.SSH_KEY }}
          registry: MyOrg/MyRegistry
      - uses: julia-actions/setup-julia@v1
        with:
          version: 1
      - uses: julia-actions/julia-runtest@v1

The order doesn't matter, Julia needn't be installed to run this action.
