// UpdateIntegratedValidatorGroups updates the integrated validator groups for a specified account.
// It retrieves the account associated with the provided userID, then updates the integrated validator groups
// with the provided list of group ids. The updated account is then saved.
//
// Parameters:
//   - accountID: The ID of the account for which integrated validator groups are to be updated.
//   - userID: The ID of the user whose account is being updated.
//   - groups: A slice of strings representing the ids of integrated validator groups to be updated.
//
// Returns:
//   - error: An error if any occurred during the process, otherwise returns nil
