IntelliSense for module versions in private registry

[eric-ash-1]

Is your feature request related to a problem? Please describe.
We use an Azure Container Registry for our company's Bicep code. It's frustrating to use compared with the usual "resource" experience, which gives you suggestions about the available API versions after you type the "@". When using ACR, you get no IntelliSense suggestions after typing the colon.

Describe the solution you'd like
After typing the colon (i.e. the portion below), Intellisense would show you the available versions of the module and filter them further as you typed.

module storage1 'br:myacr.azurecr.io/bicep/storage:

Same idea if you had an alias defined in bicepconfig.json, it would make suggestions after typing the last colon:

module storage1 'br/MyRegistry:storage:

This is a duplicate. Closing this in favor of #9038 which is in our backlog. We plan to make progress in the next few months.
