Should Microsoft.ServiceFabricManagedClusters folder be Microsoft.ServiceFabric?

As described in https://github.com/Azure/azure-rest-api-specs#directory-structure, this repo is fairly consistent about the folder structure. In particular, item (4) is a resource provider name. For service fabric managed clusters, the resource provider is still called `Microsoft.ServiceFabric` ([example](https://github.com/Azure/azure-rest-api-specs/blob/9816073fe0652b346f5bf328a7ba017efcb7e826/specification/servicefabricmanagedclusters/resource-manager/Microsoft.ServiceFabricManagedClusters/stable/2021-05-01/managedcluster.json#L37)) while the folder is called `Microsoft.ServiceFabricManagedClusters`: https://github.com/Azure/azure-rest-api-specs/tree/main/specification/servicefabricmanagedclusters/resource-manager/Microsoft.ServiceFabricManagedClusters

Shall it be renamed to `Microsoft.ServiceFabric`?

This triggered an error in [Pulumi Azure Native provider](https://github.com/pulumi/pulumi-azure-native/).

Start with the directory-structure guidance and compare specification/servicefabricmanagedclusters/resource-manager/Microsoft.ServiceFabricManagedClusters with managedcluster.json, especially its resource-provider reference. Check for references to the existing folder name before deciding whether the directory should use Microsoft.ServiceFabric. Done means the folder naming is consistent and the related specification links or checks still resolve.
