gh-aw workshop docs incorrect #56618

Reproduction steps:

• on https://githubnext.github.io/gh-aw-workshop/#06-install-gh-aw the section "Initialize agentic workflow skills" lists multiple artifacts that should be created when running gh aw init
• the artifacts that are mentioned are:
  • .github/skills/agentic-workflows/SKILL.md
  • .github/skills/agentic-workflow-designer/SKILL.md
  • .github/agents/agentic-workflows.md
  • .github/mcp.json
  • .github/workflows/copilot-setup-steps.yml
  • .vscode/settings.json
• however, multiple artifacts are in fact not created after running gh aw init
• the artifacts that are created are:
  • .github/skills/agentic-workflows/SKILL.md
  • .vscode/settings.json
  • .gitattributes

Acceptance criteria:

• from the documentation page, remove the artifacts that are not created and keep only the ones that are created
