Support for AWSManagedRulesBotControlRuleSet under ManagedRuleGroupConfig

### Name of the resource

AWS::WAFv2::WebACL

### Resource name

ManagedRuleGroupConfig

### Description

Using `UpdateWebACL` API call we can set `AWSManagedRulesBotControlRuleSet` under Managed Rule Group Configs as below

```
"ManagedRuleGroupConfigs": [
{
"AWSManagedRulesBotControlRuleSet": {
"InspectionLevel": "string"
},
"LoginPath": "string",
"PasswordField": {
"Identifier": "string"
},
"PayloadType": "string",
"UsernameField": {
"Identifier": "string"
}
}
]
```
However, If we use the same definition in CloudFormation stack and perform a stack update for `AWS::WAFv2::WebACL` resource we would get ***InvalidReqeust*** error

```
Resource handler returned message: "Model validation failed (#: extraneous key [AWSManagedRulesBotControlRuleSet] is not permitted)" (
```
because CloudFormation supports only below attributes in the syntax for `ManagedRuleGroupConfig` under `ManagedRuleGroupStatement`
```
{
"LoginPath" : String,
"PasswordField" : FieldIdentifier,
"PayloadType" : String,
"UsernameField" : FieldIdentifier
}

- The cloudformation template used while testing this behavior

```

**ASK**
- It would be helpful If we can set the property `AWSManagedRulesBotControlRuleSet` under Managed Rule Group Config

### Other Details

https://docs.aws.amazon.com/waf/latest/APIReference/API_UpdateWebACL.html

Start by comparing the AWS::WAFv2::WebACL ManagedRuleGroupConfig CloudFormation documentation with the UpdateWebACL API example and the supplied template. Done means the AWSManagedRulesBotControlRuleSet property with InspectionLevel is accepted under ManagedRuleGroupConfigs and no longer produces the extraneous-key validation error.
