aws-backup: Parameter names with incorrect casing for AWS::Backup::Framework L1 construct in Python

### Describe the bug

Can not deploy AWS Backup Audit Manager Framework using the L1 construct

The issue is that the property name for the sub type `FrameworkControl.ControlScope.ComplianceResourceTypes` is synthesized as complianceResourceTypes (lowercase c) and CFN will fail validation.

### Expected Behavior

L1 construct for `AWS::Backup::Framework.FrameworkControl.ControlScope.ComplianceResourceTypes` would synth with the correct casing

``` json
"DefaultFramework": {
"Type": "AWS::Backup::Framework",
"Properties": {
"FrameworkControls": [
{
"ControlInputParameters": [],
"ControlName": "BACKUP_RESOURCES_PROTECTED_BY_BACKUP_PLAN",
"ControlScope": {
"ComplianceResourceTypes": [ // <-- Expect Upper Case "C"
"RDS"
]
}
}
]
}
}
```

- [ ]

### Current Behavior

L1 construct for `AWS::Backup::Framework.FrameworkControl.ControlScope.ComplianceResourceTypes` synth produces the following with a lowercase "c"

``` json
"DefaultFramework": {
"Type": "AWS::Backup::Framework",
"Properties": {
"FrameworkControls": [
{
"ControlInputParameters": [],
"ControlName": "BACKUP_RESOURCES_PROTECTED_BY_BACKUP_PLAN",
"ControlScope": {
"complianceResourceTypes": [ // <-- Produces lower case "c"
"RDS"
]
}
}
]
}
}
```

``` shell
# cdk deploy

...

The stack named backup-audit-sandpit failed creation, it may need to be manually deleted from the AWS console: ROLLBACK_COMPLETE: Properties validation failed for resource Framework with message:
#/FrameworkControls/1/ControlScope: extraneous key [complianceResourceTypes] is not permitted
```

### Reproduction Steps

``` python
from aws_cdk import (
aws_backup as backup,
Stack,
App,
)

class BackupAudit(Stack):
def __init__(self, app: App, id: str, **kwargs) -> None:
super().__init__(app, id, **kwargs)

default_framework = backup.CfnFramework(
self,
"DefaultFramework",
framework_controls=[
backup.CfnFramework.FrameworkControlProperty(
control_name="BACKUP_RESOURCES_PROTECTED_BY_BACKUP_PLAN",
control_input_parameters=[],
control_scope=backup.CfnFramework.ControlScopeProperty(
compliance_resource_types=[
"RDS",
"Aurora",
"EFS",
"EC2",
"EBS",
"DynamoDB",
"FSx",
],
),
),
],
)

app = App()

BackupAudit(app, "backup-audit-sandpit")

app.synth()
```

### OS

Ubuntu 22.04 (WSL)

### Language

### Language Version

Python 3.10.12

### Other information

Passing a raw dictionary into `control_scope` with the correct key values will produce the correct CFN output

The issue only seems to occur when you use the `backup.CfnFramework.ControlScopeProperty()` class as an input

Start with the Python entry point backup.CfnFramework.ControlScopeProperty and reproduce the synthesized output using the example in the issue. Trace how compliance_resource_types becomes complianceResourceTypes; done when the synthesized AWS::Backup::Framework uses ComplianceResourceTypes and the reported deployment validation error is resolved.
