jekyll-github-metadata calls Pages API for private repos with Pages disabled, causing fatal 403 #302

Description

When a repo is private and GitHub Pages is not enabled, the jekyll-github-metadata gem (v2.16.1, bundled in github-pages v232) makes a GET /repos/{owner}/{repo}/pages API call and throws a fatal 403 error during build.

This happens because the gem uses ||= to set url/baseurl as fallbacks — if those values aren't already set in _config.yml, it tries to detect them via the Pages API. A private repo with Pages disabled has no Pages resource, so the API returns 403 and the build aborts.

Environment

• jekyll-github-metadata v2.16.1
• github-pages v232
• Private repo with GitHub Pages disabled

Steps to reproduce

1. Create a private repo with GitHub Pages disabled.
2. Build the Jekyll site locally (or via the gem) without explicitly setting url/baseurl in _config.yml.

Expected

The gem falls back gracefully (e.g. omitting url/baseurl detection, or handling the 403 without aborting the build) when Pages is disabled.

Actual

The build aborts with a fatal 403 error from the GET /repos/{owner}/{repo}/pages call.

Workaround

Setting url and baseurl explicitly in _config.yml short-circuits the ||= fallback, so the Pages API is never called. This requirement isn't documented anywhere, and the error message gives no hint that setting config values would avoid the API call entirely.
