Flattened output in the workspace output action

The output produced by the workspace-output is flattened. For example I have the following output values defined in tf:

```
output "url" {
value = {
"url" = "url"
}

}

output "username" {
value = {
"username" = "username"
}

}

output "password" {
value = {
"password" = "password"
}

}
```
and the output I get from the action is:
`[name:password,name:url,name:username] [name:password,name:url,value:{username:username}] [name:password,value:{url:url},name:username] [name:password,value:{url:url},value:{username:username}] [value:{password:password},name:url,name:username] [value:{password:password},name:url,value:{username:username}] [value:{password:password},value:{url:url},name:username] [value:{password:password},value:{url:url},value:{username:username}]`
