How do I update github actions to Node.js 20?

I’ll try, but as I say, I’m a little unsure whether I’m understanding correctly. I wrote an updat to my julia package a couple of days ago, and the nightly ubuntu-latest test run failed. The message is currently:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: julia-actions/setup-julia@latest, actions/cache@4d4ae6ae148a43d0fd1eda1800170683e9882738, pyTooling/Actions/with-post-step@adef08d3bdef092282614f3b683897cefae82ee3.

This message is the response to my latest changes to CI.yml, which currently reads:

jobs:
  test:
    name: Julia ${{ matrix.version }} - ${{ matrix.os }} - ${{ matrix.arch }} - ${{ github.event_name }}
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        version:
          - '1'
          - 'nightly'
        os:
          - ubuntu-latest
        arch:
          - x64
    steps:
      - uses: actions/checkout@v4
      - uses: julia-actions/setup-julia@latest
        with:
          version: ${{ matrix.version }}
          arch: ${{ matrix.arch }}
      - uses: julia-actions/cache@v1
      - uses: julia-actions/julia-buildpkg@latest
      - uses: julia-actions/julia-runtest@latest

At the moment I’ve come to a standstill - can you help?
(Btw, I’m driving from Germany to Britain over the next two days, so my responses may be slow)
