Rule 944140 (#4548) was not backported as it does not exist in v3.3. * ci(lint): prevent duplicate workflow runs on PRs Restrict push trigger to v3.3/dev and v3.3/master branches so that pull requests only trigger the workflow once via the pull_request event, instead of running both push and pull_request. --------- Signed-off-by: Felipe Zipitria <felipe.zipitria@owasp.org>
