What does this MR do and why?

This is the second step of #23605 (closed).

1. Add auto cancel pipeline on job failure syntax ... (!137815 - merged)
2. <-- HERE -->
3. Added documentation for workflow:auto_cancel:on... (!145709 - merged)

This MR uses the workflow:auto_cancel:on_job_failure setting that was introduced in !137815 (merged) to stop the pipeline as soon as a job fails.

How to set up and validate locally

Set up a pipeline with the workflow:auto_cancel:on_job_failure set to all and to have more than one job, one of which has to fail. The whole pipeline should be cancelled after the job fails.

This is an example .gitlab-ci.yml

stages:
  - build
  - test
  - deploy

workflow:
  auto_cancel:
    on_job_failure: all

build-a:
  stage: build
  script:
    - echo "Building a..."
    - sleep 5
    - echo "Done"

build-b:
  stage: build
  script:
    - echo "Building b..."
    - exit 1

build-c:
  stage: build
  script:
    - echo "Building c..."
    - sleep 5
    - echo "Done"

build-d:
  stage: build
  script:
    - echo "Building d..."
    - sleep 5
    - echo "Done"

build-e:
  stage: build
  script:
    - echo "Building e..."
    - sleep 5
    - echo "Done"
lint:
  stage: test
  script:
    - echo "Linting..."
    - echo "Done"

deploy:
  stage: deploy
  script:
    - echo "Deploying..."
    - echo "Done..."
