`OpenAPI.yaml`の`getUserDMChannel`のuserIdがUUIDになっていない

[pikachu0310]

実際にはUUID

// GetUserDMChannel GET /users/:userID/dm-channel
func (h *Handlers) GetUserDMChannel(c echo.Context) error {
userID := getParamAsUUID(c, consts.ParamUserID)
myID := getRequestUserID(c)

// DMチャンネルを取得
ch, err := h.ChannelManager.GetDMChannel(myID, userID)
if err != nil {
	return herror.InternalServerError(err)
}

return c.JSON(http.StatusOK, &DMChannel{ID: ch.ID, UserID: userID})

}
