guacamole-azure-linuxvm user service initializes Terraform with the same backend key as the Windows VM

[SvenAelterman]

Describe the bug

I don't know if this is a real issue. But if it's meant to be generic, perhaps the OS could be removed from the key value?

Steps to reproduce

See this line of code:

AzureTRE/templates/workspace_services/guacamole/user_resources/guacamole-azure-linuxvm/terraform/deploy.sh

Line 16 in d90d492

-backend-config="key=${TF_VAR_tre_id}${TF_VAR_workspace_id}${TF_VAR_parent_service_id}guacamolewindowsvm"

Thank you for this.
This might be an issue for a developer running terraform commands directly. There's no issue with the bundle.
