Enable GitHub Pages in repository settings

[oliynykmax]

The GitHub Pages site needs to be enabled in order for the CI/CD deployment () to work.

The workflow's build step passes successfully, but the deploy step fails with:

Error: Failed to create deployment (status: 404)
Ensure GitHub Pages has been enabled: https://github.com/microsoft/RustTraining/settings/pages

A series of PRs has been made to set up automatic deployment:

• PR Found repo, no pages deployed #23: Added the GitHub Actions workflow
• PR Fix mdbook installation in CI #33: Fixed mdbook installation (--force flag)

To complete the setup, please enable GitHub Pages:

1. Go to Settings > Pages
2. Set Source to "GitHub Actions"

This will allow the workflow to deploy the documentation automatically on every push to main.

This is a repository settings change, not a code fix — it needs a maintainer to go to Settings → Pages and set the source to GitHub Actions. Tagging @atulkhare4096 for visibility.
