Alert Rules + Autocomplete produces invalid syntax

**Bicep version**
run `bicep --version` via the Bicep CLI, `az bicep version` via the AZ CLI or via VS code by navigating to the extensions tab and searching for Bicep

**Describe the bug**
When setting up a `alertRules` through VSCode you are prompted with these three options, all which produce an invalid syntax with `odata.context`.



**To Reproduce**
Steps to reproduce the behavior:

Start with the following code:
```bicep

resource test 'Microsoft.Insights/alertrules@2016-03-01' ={
name: 'test'
location: 'eastus'
properties: {
condition: // put text cursor here and try to auto complete
isEnabled: true
name: 'test'
}
}

```

It should produce:

```bicep
resource test 'Microsoft.Insights/alertrules@2016-03-01' ={
name: 'test'
location: 'eastus'
properties: {
condition: {
odata.type: 'Microsoft.Azure.Management.Insights.Models.LocationThresholdRuleCondition' // ERR - Property has a dot
failedLocationCount:
}
isEnabled: true
name: 'test'
}
}
```

Start by reproducing the issue in VS Code with the provided Microsoft.Insights/alertrules resource and inspect the autocomplete suggestions for the condition property. Trace the resource schema or language-service entry point that generates those snippets; done means each suggestion produces valid Bicep syntax without a dotted property name such as odata.type.
