CI: pin GitHub Actions workflows #244

Closed ErikSchierboom closed 7 months ago

ErikSchierboom commented 7 months ago

This PR updates GitHub Actions workflows to a specific version. This ensures that the workflow will always run the same code, which makes your build stable. It will also prevent a potential security issue where a tag could be replaced by a malicious commit without consumers being aware of it.

The PR updates each non-SHA based workflow reference with the SHA of the referenced version/tag, so the current behavior should not change.

See https://exercism.org/docs/building/github/gha-best-practices#h-pin-actions-to-shas for more information.
