Update network-watcher-packet-capture-manage-cli.md

I added a command for showing the Network Watcher extension for a Linux VM, as the difference in naming (e.g. AzureNetworkWatcherExtension for Linux) causes confusion when referencing the name of the extension on Windows.  Additionally, I may be mistaken, but I think the existing Step 1 under "Start a packet capture" is unnecessary.  "az network watcher show" is invalid.  Also, I changed "Start a packet capture" step 2 to retrieve the storage account with "az storage account list" instead of "azure storage account list".  Finally, I changed references to 'cmdlet' to 'command' to make it more consistent for the CLI portion of the documentation.

 Filters can be used to limit the data that is stored by the packet capture. The following example sets up a packet capture with several  filters.  The first three filters collect outgoing TCP traffic only from local IP 10.0.0.3 to destination ports 20, 80 and 443.  The last filter collects only UDP traffic.
 
 ```azurecli
 az network watcher packet-capture create --resource-group {resourceGroupName} --vm {vmName} --name packetCaptureName --storage-account {storageAccountName} --filters "[{\"protocol\":\"TCP\", \"remoteIPAddress\":\"1.1.1.1-255.255.255\",\"localIPAddress\":\"10.0.0.3\", \"remotePort\":\"20\"},{\"protocol\":\"TCP\", \"remoteIPAddress\":\"1.1.1.1-255.255.255\",\"localIPAddress\":\"10.0.0.3\", \"remotePort\":\"80\"},{\"protocol\":\"TCP\", \"remoteIPAddress\":\"1.1.1.1-255.255.255\",\"localIPAddress\":\"10.0.0.3\", \"remotePort\":\"443\"},{\"protocol\":\"UDP\"}]"
