Convert TEXT MARKDOWNSTRICT to TEXI

The TEXT file extension, associated with Unextended Markdown Documentation, is used for plain text files that contain Markdown-formatted text. Markdown is a lightweight markup language designed to be easily readable and writable, enabling users to format text using simple syntax. These files are widely used for documentation, notes, and content creation due to their simplicity and portability across different platforms and applications.

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.
