Add Agentic Workflows as a new resource type

Add support for contributing Agentic Workflows — AI-powered repository
automations that run coding agents in GitHub Actions, defined in markdown
with natural language instructions (https://github.github.com/gh-aw).

Changes:
- Create workflows/ directory for community-contributed workflows
- Add workflow metadata parsing (yaml-parser.mjs)
- Add workflow README generation (update-readme.mjs, constants.mjs)
- Add workflow data to website generation (generate-website-data.mjs)
- Update README.md, CONTRIBUTING.md, and AGENTS.md with workflow docs,
  contributing guidelines, and code review checklists
