fix: Fix deletion protection for Azure storage

[flamarion]

It is not possible lock the container, only Storage accounts

To protect the container, broader research must determine if using an Immutability policy on a container can resolve this topic.

But Terraform AzureRM don't support container immutability policies yet.

In the same issue above, there's a solution based on az_api provider that eventually can help if the solution is Immutability policy

We should have this level of protection anyway. I think it's reasonable to add a backlog item to look at the feasibility of using immutability policies on the containers/blob versions.
