JSDoc comments are incorrectly downleveled

[ImRodry]

I recently came across an issue with this package where JSDoc comments in getters would get incorrectly downleveled and become regular multi-line comments, which lose all the properties of a JSDoc comment. Here's an example of that taken from the bson package

declare class ObjectId {
	/**
	 * The generation time of this ObjectId instance
	 * @deprecated Please use getTimestamp / createFromTime which returns an int32 epoch
	 */
	get generationTime(): number;
	set generationTime(value: number);
}

becomes

declare class ObjectId {
	/*
	* The generation time of this ObjectId instance
	* @deprecated Please use getTimestamp / createFromTime which returns an int32 epoch
	*/
	generationTime: number;
}
