Add detailed docstrings:

• Added high-level explanation of the plugin’s purpose.
• Documented supported GitHub shorthand link formats:
  • gh-issue
  • gh-pr
  • gh-project
  • gh-dir
  • gh-file
• Described the logic of inline and auto-link transformations.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Summary of Changes

Hello @windsonsea, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses entirely on improving the documentation and readability of the url_schemes.py file, which contains a custom MkDocs plugin hook. My aim was to make the code easier to understand for new contributors and future maintainers by adding detailed docstrings, inline comments, and type hints, without introducing any changes to the existing logic or behavior.

Highlights

• Documentation Enhancement: Added a comprehensive docstring to the on_page_markdown function in url_schemes.py, detailing its purpose as a custom MkDocs plugin hook for rewriting GitHub shorthand links.
• Clarity on Link Formats: The new docstring explicitly lists and explains the supported GitHub shorthand link formats, such as gh-issue, gh-pr, gh-project, gh-dir, and gh-file, along with examples of their transformation.
• Internal Function Documentation: Docstrings were added to the replace_inline_link and replace_auto_link helper functions, clarifying their roles in processing different types of GitHub shorthand links.
• Code Readability: Inline comments were added to explain key sections of the code, such as the urls mapping, the regular expression for shorthand links, and the final replacement steps.
• Type Hinting: A return type annotation (-> str) was added to the on_page_markdown function signature for improved type clarity.

Code Review

This pull request significantly improves the readability of url_schemes.py by adding comprehensive docstrings and comments. The documentation is clear and helpful for understanding the script's functionality. I've made one suggestion to correct an example in the main docstring for consistency and accuracy. Great work on enhancing the project's documentation!
