Convert MD GFM to TEXI

Markdown (MD) is a lightweight markup language with a file extension MD, commonly used for formatting readme files, documentation, and comments in GitHub repositories. GitHub-Flavored Markdown (GFM) extends the original Markdown's capabilities, adding features like tables, task lists, and auto-linking URLs. Markdown's simplicity and effectiveness in creating formatted text using a plain text editor made it widely adopted in the developer community. GFM, in particular, is optimized for use on GitHub, enhancing collaboration and code documentation.

The TEXI file extension, short for Texinfo, is a documentation format used primarily by the GNU Project for creating software manuals. Developed by Richard Stallman and Bob Chassell, it organizes content into a book-like structure and allows a single source file to generate both online and printed documentation. TEXI files are widely used in open-source projects and are recognized by their TEXI extension.
