ci: fix pull_request_target fork checkout error and Node 20 deprecation
warning (#324)

Fixes:
- The Jenkins dispatch workflow failed on fork PRs with
  Error: Refusing to check out fork pull request code from a
  'pull_request_target' workflow. This workflow runs with the base
  repository's GITHUB_TOKEN, secrets, default-branch cache scope, and
  runner access. Fetching and executing a fork's code in that trusted
  context commonly leads to "pwn request" vulnerabilities. To opt in,
  review the risks at https://gh.io/securely-using-pull_request_target
  and set 'allow-unsafe-pr-checkout: true' on the actions/checkout step.
- Node 20 warnings on GitHub Actions
