[Microsoft.App/containerApps@2023-05-01]: The property "cpu" expected a value of type "int | null" but the provided value is of type "'0.5'".

### Resource Type

Microsoft.App/containerApps

### Api Version

2023-05-01

### Issue Type

Inaccurate property type(s)

### Other Notes

Maybe this type should just be a string, since Bicep doesn't support double?
At the very least, the value is valid so the warning should not appear.

### Bicep Repro

```
resource containerApp 'Microsoft.App/containerApps@2023-05-01' = {
name: 'TodoApp'
location: location
identity: {
type: 'SystemAssigned'
}
properties: {
managedEnvironmentId: ace.id
configuration: {
dapr: {
enabled: false
}
}
template: {
containers: [
{
name: 'TodoAppContainer'
image: 'mcr.microsoft.com/azuredocs/containerapps-helloworld:latest'
resources: {
cpu: '0.5'
memory: '1Gi'
}
}
]
}
}
```
### Confirm

- [X] I have read the troubleshooting guide and looked for duplicates.

Start with the Microsoft.App/containerApps@2023-05-01 definition and the supplied Bicep repro, checking how the cpu property is typed. Confirm the expected behavior for the '0.5' value and update the definition so the valid repro no longer produces the warning; verify with the same repro.
