containerApps: properties.runningStatus is missing

### Resource Type

Microsoft.App/containerApps

### Api Version

2024-03-01

### Issue Type

Missing property(s)

### Other Notes

properties.runningStatus is missing

runningStatus is flagged as not allowed, but a what-if command says it is fine.
`Warning BCP037: The property "runningStatus" is not allowed on objects of type "ContainerAppProperties". Permissible properties include "managedEnvironmentId".`

This is needed for container apps that should be deployed in a stopped mode so a logic app can start and stop them.

### Bicep Repro

```bicep
resource containerApp 'Microsoft.App/containerApps@2024-03-01' = {
name: appName
location: location
properties: {
...
runningStatus: 'Stopped'
}
}
```

### Confirm

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

Start with the Microsoft.App/containerApps type definition for API version 2024-03-01 and compare it with the Bicep repro in the issue. Confirm that adding properties.runningStatus with value 'Stopped' is accepted and that the repro no longer emits BCP037.
