/**
 * Middleware function to parse raw text body in HTTP requests.
 *
 * This middleware function will read the raw text body from the request and
 * set it as the `req.body` property if the `Content-Type` header is 'text/plain'
 * or not specified. If the `Content-Type` is something else, it will call the
 * next middleware function without modifying the request body.
 *
 * @param {Request} req - The Express request object.
 * @param {Response} _res - The Express response object.
 * @param {NextFunction} next - The next middleware function.
