(aws_elasticache): CfnUser.AuthenticationModeProperty incorrectly synthesizes Type

[FarrOut]

Describe the bug

CfnUser.AuthenticationModeProperty incorrectly synthesizes to type rather than Type.

Expected Behavior

  "ECadmin": {
   "Type": "AWS::ElastiCache::User",
   "Properties": {
    "AccessString": "on ~* +@all",
    "AuthenticationMode": {
     "Type": "iam"
    },
    "Engine": "redis",
    "NoPasswordRequired": false,
    "UserId": "ec-admin",
    "UserName": "ec-admin"
   },

Current Behavior

"ECadmin": {
   "Type": "AWS::ElastiCache::User",
   "Properties": {
    "AccessString": "on ~* +@all",
    "AuthenticationMode": {
     "type": "iam"
    },
    "Engine": "redis",
    "NoPasswordRequired": false,
    "UserId": "ec_admin",
    "UserName": "ec_admin"
   },

UPDATE_FAILED        | AWS::ElastiCache::User     | ElastiCacheNestedStack/ECadmin (ECadmin) Properties validation failed for resource ECadmin with message:
#/AuthenticationMode: required key [Type] not found
#/AuthenticationMode: extraneous key [type] is not permitted

Reproduction Steps

        admin_user = elasticache.CfnUser(
            self,
            "ECadmin",
            engine="redis",
            user_id="ec-admin",
            user_name="ec-admin",
            access_string="on ~* +@all",
            authentication_mode=elasticache.CfnUser.AuthenticationModeProperty(
                type="iam",
            ),
            no_password_required=False
        )

Possible Solution

admin_user = elasticache.CfnUser(
    self,
    "ECadmin",
    engine="redis",
    user_id="ec-admin",
    user_name="ec-admin",
    access_string="on ~* +@all",
    authentication_mode= {"Type": "iam"},
    no_password_required=False
)

authentication_mode is type Any(doc) and you will need to pass a JSON instead

I think your possible solution should work.
