Update workflow dependencies to newer major versions in repository automation files. This upgrades `actions/checkout` to v7, `actions/github-script` to v9, `actions/create-github-app-token` to v3, and GitHub Pages actions (`upload-pages-artifact` and `deploy-pages`) to v5 to keep CI/CD and maintenance workflows current.
- close-new-script-prs: trigger on added script file OR label, exempt by
author_association (OWNER/MEMBER/COLLABORATOR) instead of team API
- close_issue_in_dev: match VED issues by derived slug, close all matches
- lock-issue: lock closed issues after 7 days instead of 3
