Mismatch type description for Cognito CognitoEventUserPoolsPreTokenGenV2 Event

[AbhigyaKrishna]

There is a type mismatch for claims_to_add_or_override in CognitoEventUserPoolsPreTokenGenV2 event. claims_to_add_or_override should accept any of the json types instead of only strings.

The documentation at AWS mentions the following type description for the event as:

{
    "request": {
        "userAttributes": {
            "string": "string"
        },
        "scopes": ["string", "string"],
        "groupConfiguration": {
            "groupsToOverride": ["string", "string"],
            "iamRolesToOverride": ["string", "string"],
            "preferredRole": "string"
        },
        "clientMetadata": {
            "string": "string"
        }
    },
    "response": {
        "claimsAndScopeOverrideDetails": {
            "idTokenGeneration": {
                "claimsToAddOrOverride": {
                    "string": [accepted datatype]
                },
                "claimsToSuppress": ["string", "string"]
            },
            "accessTokenGeneration": {
                "claimsToAddOrOverride": {
                    "string": [accepted datatype]
                },
                "claimsToSuppress": ["string", "string"],
                "scopesToAdd": ["string", "string"],
                "scopesToSuppress": ["string", "string"]
            },
            "groupOverrideDetails": {
                "groupsToOverride": ["string", "string"],
                "iamRolesToOverride": ["string", "string"],
                "preferredRole": "string"
            }
        }
    }
}

Accepted datatypes:

• String
• Number
• Boolean
• Array of strings, numbers, booleans, or a combination of any of these
• JSON

Proposed Solution

- pub claims_to_add_or_override: HashMap<String, String>
+ pub claims_to_add_or_override: HashMap<String, serde_json::Value>
