keyvault-managed storage account

**Is your feature request related to a problem? Please describe.**
looking for solution with .bicep example of creating a keyvault-managed storage account for auto generation of keys of storage account managed by key vault with respect to regeneration period specified.

NOTE: solution available through Azure CLI (https://docs.microsoft.com/en-us/azure/key-vault/secrets/overview-storage-keys), looking for the same through bicep template.

FYI, Found an Issue (https://github.com/Azure/bicep/issues/4608 ), looks like created for 2 things mentioned below, out of 2, one got resolved, other seems to be not clear, so opened this issue for more clarity.

1. bicep template for keyvault-managed storage account. [ not clearly described in #4608 ]
2. storage account encryption using customer managed key present in key vault. [ Resolved with Quick Start Template provided recently through #4608 ] thanks for @stan-sz , @egullbrandsson , @StefanIvemo

**Describe the solution you'd like**
.bicep example of creating a keyvault-managed storage account for auto generation of keys of storage account managed by key vault with respect to regeneration period specified.

Start by reviewing the Azure CLI storage-key management documentation linked in the issue and the related Azure/bicep issue #4608. Done means providing a clear Bicep example for a Key Vault-managed storage account with the requested key regeneration period, while distinguishing it from customer-managed-key encryption.
