Feat: add the possibility to skip a failed test from a matrix

[alber70g]

Imagine this

  end-to-end-tests:
    name: E2E - ${{ matrix.app }}
    needs: build
    runs-on: ubuntu-latest
    strategy:
      fail-fast: false
      matrix:
        app: ['tools', 'docs', 'app']

and the ci-gate

  ci-gate:
    if: always()
    needs:
      - build
      - integration-tests
      - end-to-end-tests
    runs-on: Ubuntu-latest
    steps:
      - name: Check required jobs.
        uses: re-actors/alls-green@release/v1
        with:
          jobs: ${{ toJSON(needs) }}

I'd like to be able to "allow-failed" the app part of end-to-end-tests. Is that possible?

You'll have to do this on the matrix definition level. It is technically impossible for this action to have visibility into how your jobs are set up.

I think there's an example of a "continue on fail" somewhere in the readme.
