Index loops not providing correct what if resource creation/modification count.

**Describe the bug**
While Using a loop index on a count defined in a variable the `--confirm-with-what-if -c` flags do not show the correct item count and the print-out does not reflect any of the changes

**To Reproduce**
All resources are created as expected however the what-if explanation does not correctly show the changed resources.
```
resource vmNIC 'Microsoft.Network/networkInterfaces@2020-11-01' = [for vmNumber in range(0, vmCount) : {
name: 'nic-${vmName}-${vmNumber}'
location: deployLocation
properties: {
ipConfigurations: [
{
name: 'Main'
properties: {
privateIPAllocationMethod: 'Dynamic'
subnet: {
id: resourceId('Microsoft.Network/virtualNetworks/subnets', vmNetwork, vmSubnet)
}
publicIPAddress: vmHasPublic ? {
id: vmpublicIPAddress[vmNumber].id
} : null
}
}
]
}
}]
```

**Expected behavior**
The what-if flag will contain the resources that are configured for looping
