/*


First, the `getLanguageCode` function extracts the language code from the file content using a regular expression. The `updateMdFile` function then updates the file's `slug` and `path` values with the language code. Finally, the `findAndUpdateMdFiles` function recursively searches through the provided directory and its subdirectories, updating all `.md` files it encounters.

To use the function, call `findAndUpdateMdFiles('/your/path/here');`, replacing `/your/path/here` with the desired path.
