refactor(projects): rename pages section to projects with contributions

- rename content/page/pages → content/page/projects, keep /pages alias
- list owned + contributed repos (GraphQL repositoriesContributedTo)
- filter by URL (homepage or has_pages), not just GitHub Pages enabled
- rename script/workflow to update-projects-list.mjs / update-projects.yml
