### (Optional) Module Version

### Description

According to this [parameter description](https://github.com/Azure/bicep-registry-modules/blob/3385341b7cdd437703e65ace083ac5b86be990ce/avm/res/cognitive-services/account/main.bicep#L129), the deployments parameter should be an array and looking at [this](https://github.com/Azure/bicep-registry-modules/blob/3385341b7cdd437703e65ace083ac5b86be990ce/avm/res/cognitive-services/account/main.bicep#L359) bicep code, it seems that it _should_ work fine if I set my deployments array up like this.

```
deployments: [
{
model: {
name: 'gpt-35-turbo'
format: 'OpenAI'
version: '0125'
}
sku: {
name: 'Standard'
capacity: 8
}
}
{
model: {
name: 'dall-e-3'
format: 'OpenAI'
version: '3.0'
}
sku: {
name: 'Standard'
capacity: 1
}
}
]
```

But it does not work and get the following error message:

```
ERROR: error executing step command 'provision': deployment failed: error deploying infrastructure: deploying to subscription:

Deployment Error Details:
InvalidTemplate: Deployment template validation failed: 'The resource 'Microsoft.CognitiveServices/accounts/aoai-devdtzp/deployments/aoai-devdtzp-deployments' at line '1' and column '34876' is defined multiple times in a template. Please see https://aka.ms/arm-syntax-resources for usage details.'.
```

If I remove my `dall-e-3` deployment from the array, then it works fine.
