[BUG] - Error while processing template - An item with the same key has already been added

### Describe the bug

When running analyzer against following bicep template I'm getting 'An item with the same key has already been added' exception.

Bicep template:

```
@description('EventHub Namespace name')
param namespace string

@description('Specifies the Azure location for all resources.')
param location string = resourceGroup().location

@description('Specifies the messaging tier for Event Hub Namespace.')
@allowed([
'Basic'
'Standard'
])
param eventHubSku string = 'Standard'

param storageAccountName string

param additionalTags object = { ROLE_PURPOSE: 'Test Event Hub' }

@description('Capacity')
param capacity int = 1
param messageRetention int = 7

param hubs array

var eventHubNamespaceName = namespace

resource eventHubNamespace 'Microsoft.EventHub/namespaces@2022-10-01-preview' = {
name: eventHubNamespaceName
location: location
tags: union(resourceGroup().tags, additionalTags)
sku: {
name: eventHubSku
tier: eventHubSku
capacity: capacity
}
properties: {
isAutoInflateEnabled: false
maximumThroughputUnits: 0
}
}

resource eventHub 'Microsoft.EventHub/namespaces/eventhubs@2022-10-01-preview' = [for hub in hubs: {
parent: eventHubNamespace
name: hub.name
properties: {
messageRetentionInDays: messageRetention
partitionCount: hub.partitionCount
}
}]

resource consumerGroup 'Microsoft.EventHub/namespaces/eventhubs/consumergroups@2022-10-01-preview' = [for (hub, i) in hubs: {
parent: eventHub[i]
name: hub.consumerGroupName
properties: {}
}]

resource container 'Microsoft.Storage/storageAccounts/blobServices/containers@2023-01-01' = [for hub in hubs: {
name: '${storageAccountName}/default/${hub.offsetContainerName}'
}]
```
