[BUG] DatabaseWatcher Enum is named "string"

### API Spec link

### Describe the bug

This newly added file defines an enum with the name "string". This seems like a mistake. It's not technically invalid but it doesn't tell the user anything and it can cause problems in programs generated from the spec, since "string" is often reserved.

```json
"targetCollectionStatus": {
"type": "string",
"description": "The target collection status.",
"enum": [
"Enabled",
"Disabled"
],
"x-ms-enum": {
"name": "string",
"modelAsString": true,
"values": [
{
"name": "Enabled",
"value": "Enabled",
"description": "Denotes a target that is enabled."
},
{
"name": "Disabled",
"value": "Disabled",
"description": "Denotes a target that is disabled."
}
]
}
},
```

### Expected behavior

The enum has a descriptive name, not a basic type name.

### Actual behavior

The enum is named "string"

### Reproduction Steps
