Subject: [PATCH] ci(codeql): analyse the workflows with CodeQL code scanning

The repository had no code scanning analysis. CodeQL now analyses the
actions language on pull requests that change a workflow, on master,
weekly and by hand, and uploads the findings. The job is not a
required check. Actions are pinned by commit.
