 * adheres to the CSVW (CSV on the Web) specifications. It validates the allowed keys,
 * object structure, inherited properties, and child elements such as `dialect`, `tables`,
 * and `transformations`. Additionally, it ensures that the table group contains at least
 * one table and has the correct type.
 *
 * @param {CsvwTableGroupDescription} tg - The table group description object to validate.
 * @param {ValidationContext} ctx - The context object containing validation utilities and an issue tracker.
 *
 * @throws Will add errors to the issue tracker in the context if validation fails.
