// This is the latest version of AWS WAF, named AWS WAFV2, released in November,
// 2019. For information, including how to migrate your AWS WAF resources from
// the prior release, see the AWS WAF Developer Guide (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html).
//
// Updates the specified RuleGroup.
//
// A rule group defines a collection of rules to inspect and control web requests
// that you can use in a WebACL. When you create a rule group, you define an
// immutable capacity limit. If you update a rule group, you must stay within
// the capacity. This allows others to reuse the rule group with confidence
// in its capacity requirements.
//
//    // Example sending a request using UpdateRuleGroupRequest.
//    req := client.UpdateRuleGroupRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
//    }
