P2 Badge Use a trigger that can receive the app credentials

Because this job is restricted to Dependabot-authored pull_request_target runs, GitHub does not expose configured secrets in this context (GitHub docs). That means semver patch/minor Dependabot PRs will reach actions/create-github-app-token with empty app-id/private-key inputs, so the approval and auto-merge steps never run; use an event/secret setup that is available to Dependabot before switching these steps to the app token.
