Skip duplicate Github Actions runs (#2929) (#3008)

* Skip duplicate Github Actions runs (#2929)

Closes #2929

Skip conditions have been added at the step level for matrix jobs because of:
https://github.com/marketplace/actions/skip-duplicate-actions#how-to-use-skip-check-with-required-matrix-jobs

* Update the skip_duplicate_workflow_runs workflow

Remove the `cancel_others` setting since cancelling workflow runs from outdated commits requires the `actions: write` permission.
