Cancellation of previous workflow runs with GH Actions

[lars-reimann]

Describe the bug
The example workflow for GitHub actions contains the following section:

# Cancel duplicate jobs: https://github.com/fkirc/skip-duplicate-actions#option-3-cancellation-only
cancel_duplicates:
  name: Cancel duplicate jobs
  runs-on: ubuntu-latest
  steps:
    - uses: fkirc/skip-duplicate-actions@master
      with:
        github_token: ${{ secrets.PAT || secrets.GITHUB_TOKEN }}

The intention behind this seems to be to cancel previous workflow runs when a push on the same branch occurs. However, the default behavior of fkirc/skip-duplicate-actions was changed in fkirc/skip-duplicate-actions#93 and the section #option-3-cancellation-only mentioned in the comment was subsequently removed in fkirc/skip-duplicate-actions#94. Now it is necessary to specifically set the option cancel_others, otherwise previous workflows run until completion.

cancel_duplicates:
  name: Cancel duplicate jobs
  runs-on: ubuntu-latest
  steps:
    - uses: fkirc/skip-duplicate-actions@master
      with:
        github_token: ${{ secrets.PAT || secrets.GITHUB_TOKEN }}
        cancel_others: true

It might be advisable to fix this dependency to a specific version (at least major + minor), since they introduce breaking changes with minor version updates.

To Reproduce
Steps to reproduce the behavior:

1. Use example workflow for GitHub Actions (also created by mega-linter-runner)
2. Push to trigger workflow
3. Push again before the previous workflow is done.

Expected behavior
Previous workflow runs should be cancelled when new pushes to the branch occur.
