Add automated RSS feed generation

Add auto-generated RSS feed for new/updated Cookbook content

Summary

This PR introduces an automated RSS (Atom-compatible) feed so users can subscribe to Cookbook updates without watching the repo or checking manually.

• Solves issue [FEATURE] Add an rss feed #2103.
• Generates rss.xml from registry.yaml + authors.yaml
• Publishes/updates the feed on every push to main via GitHub Actions
• Documents the feed URL in the README

Changes

• New: .github/scripts/generate_rss.py
  • Builds rss.xml (UTF-8, XML declaration)
  • Sorts entries by date (desc), skips archived: true
  • Uses GitHub blob links for stable item permalinks
  • Maps tags → <category> and authors → dc:creator
  • Sets channel lastBuildDate to newest entry date (or now UTC if none)
• New: .github/workflows/generate-rss.yaml
  • Runs on push to main and workflow_dispatch
  • Installs pyyaml, runs the generator, commits rss.xml if changed
• Docs: README.md
  • Adds “Subscribe to updates via RSS” with the feed URL
• Artifact: rss.xml at repo root (auto-updated by CI)

Motivation

Many users prefer a feed reader to track new tutorials, examples, and significant docs revisions. GitHub “Watch → All activity” is noisy; an RSS feed is low-friction and standard.

Implementation details

• Source of truth: registry.yaml (plus authors.yaml)
• Links: Each item links to the GitHub source (/blob/main/<path>) for stability.
• Metadata:
  • title, pubDate from entry date
  • guid is a permalink to the blob URL
  • description includes Tags and Authors
  • Dublin Core dc:creator for each author
• Limits: Emits up to 100 most recent non-archived entries.
• Namespaces: Adds dc namespace for creators.

Feed location

• Raw feed: https://raw.githubusercontent.com/openai/openai-cookbook/main/rss.xml
  (If desired later, the website can serve https://cookbook.openai.com/rss.xml by copying this file during build/deploy.)

Testing

Local

This pull request introduces automated generation and publishing of an RSS feed for the OpenAI Cookbook, making it easier for users to subscribe to updates. The main changes include adding a Python script to build the RSS feed from existing data, setting up a GitHub Actions workflow to run this script and publish rss.xml on every push to main, and updating documentation to advertise the RSS feed.

RSS Feed Generation and Automation:

• Added .github/scripts/generate_rss.py, a Python script that reads registry.yaml and authors.yaml to generate an RSS 2.0 feed (rss.xml). The feed includes metadata, links to source files, and skips archived items.
• Introduced .github/workflows/generate-rss.yaml, a GitHub Actions workflow that runs the RSS generation script on pushes to main, installs dependencies, and commits/pushes updates to rss.xml if there are changes.

Documentation Update:

• Updated README.md to include a link to the new RSS feed, allowing users to easily subscribe to cookbook updates.
