Required property 'accessTier' not filled in for storage accounts

In a bicep file, type:

resource storage 'Microsoft.Storage/storageAccounts@2023-01-01'

and press space-equals => required-properties

It gives you:

```bicep
resource storage 'Microsoft.Storage/storageAccounts@2023-01-01' = {
name:
location:
sku: {
name:
}
kind:
}
```

Fill these in, e.g.

```bicep
resource storage 'Microsoft.Storage/storageAccounts@2023-01-01' = {
name: uniqueString(resourceGroup().id, 'afsdhlga')
location: location
sku: {
name: 'Premium_LRS'
}
kind: 'BlobStorage'
}
```

and try to deploy

You get this error:

```json
{
"code": "InvalidTemplateDeployment",
"message": "The template deployment 'bicep-deploy' is not valid according to the validation procedure. The tracking id is 'b79122c9-055c-4492-80bd-c1a80c0f792d'. See inner errors for details.",
"details": [
{
"code": "PreflightValidationCheckFailed",
"message": "Preflight validation failed. Please refer to the details for the specific errors.",
"details": [

}
]
}
]
}
```

EXPECTED: Why is there no error in the bicep file if a required property is missing, and why is it not automatically added to the resource?

Start with the reported Bicep reproduction for Microsoft.Storage/storageAccounts@2023-01-01 and inspect how this resource's generated type metadata drives required-properties completion. Reproduce the deployment validation error, then determine the expected handling of accessTier; done should be defined by the issue's intended type or completion behavior and covered by a regression test if the repository provides one.
