Replace PDF parser with Markdown parser for official FAQs

- Add new markdown source file (FAQs_on_the_CRA__v12)
- Create parse-official-faqs.js to parse markdown instead of PDF
- Remove parse-official-faqs-pdf.js (old PDF parser)
- Update link-resolver.js to handle both *italics* and _italics_
- Remove pdfjs-dist and jsdom dependencies

The markdown version provides cleaner source content and eliminates
the need for complex PDF text extraction logic.
