documentation required parameters do not match criteria for synapse_workspace to be sucesfully built.

@farwind you are right. It failed when using only the required values in the documentation. I added

  identity {
    type = "SystemAssigned"
  }

and it worked. Do not know if it is documentation issue and it needs to say identity block is required or if there is a bug and if the block is not set, it needs to default to SystemAssigned. Most likely it needs to default to SystemAssigned
