Microsoft.Web/sites: missing sshEnabled

### Resource Type

Microsoft.Web/sites

### Api Version

2023-12-01

### Issue Type

Missing property(s)

### Other Notes

Adding sshEnabled: true|false to the properties object displays a warning that:

`Warning BCP037: The property "sshEnabled" is not allowed on objects of type "SiteProperties".`

However, when added it does set the SSH property correctly in the Azure portal:


### Bicep Repro

```
resource webApp 'Microsoft.Web/sites@2023-12-01' = {
name: 'appname'
location: location
identity: {
type: 'SystemAssigned'
}
kind: 'app,linux'
properties: {
siteConfig: [...]
sshEnabled: false //this gives a warning saying it is not a valid property, but it works!
}
}
```

### Confirm

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

Start by locating the Microsoft.Web/sites@2023-12-01 type definition and compare its SiteProperties schema with the Bicep repro. Verify how sshEnabled is represented by the Azure resource API, then update the definition so the repro accepts the property without BCP037; done means the warning is gone and the property remains deployable.
