**Bicep version**
v0.12.40

**Describe the bug**
the filters option is required creating a storageAccounts/managementPolicies@2022-05-01 rule. This
is not marked by the bicep Visual Studio Code extension.

**To Reproduce**
create a storageAccounts/managementPolicies@2022-05-01 resource with a rule in Visual Studio Code and the Bicep extension

Start by reproducing the issue in Visual Studio Code with the Bicep extension using a storageAccounts/managementPolicies@2022-05-01 resource containing a rule. Inspect how the extension represents the resource's filters option, and consider the issue done when the editor marks filters as required.
