Fix GitHub Pages configuration to enable website deployment

[Copilot]

This PR fixes the GitHub Pages website configuration for the machine learning lesson repository by updating the repository URL in _config.yml.

Problem

The GitHub Pages website was not accessible because the _config.yml file contained a placeholder value <USERNAME>/<PROJECT> instead of the actual repository name. This prevented Jekyll from properly building and deploying the website.

Solution

Updated the repository field in _config.yml from:

repository: <USERNAME>/<PROJECT>

to:

repository: UoA-eResearch/machine-learning-novice-sklearn-cer

Result

With this change, the GitHub Pages website should now be accessible at:
https://UoA-eResearch.github.io/machine-learning-novice-sklearn-cer/

The website includes all 8 episodes covering machine learning topics with scikit-learn:

• Introduction
• Regression
• Classification
• Clustering
• Ensemble Methods
• Dimensionality Reduction
• Ethics
• Learn More

The existing GitHub Actions workflow will automatically rebuild and deploy the site when this change is merged to the gh-pages branch.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/UoA-eResearch/machine-learning-novice-sklearn-cer/pages
  • Triggering command: curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
