Error parsing /home/runner/.terraformrc: At 3:16: illegal char

There's an error repeated in every terraform run (init / plan / apply / validate). It doesn't break the tests but it pollutes the logs.

* https://github.com/ContainerSolutions/terraform-examples/runs/3337898945?check_suite_focus=true#step:5:1036
```
There are some problems with the CLI configuration:
╷
│ Error: Error parsing /home/runner/.terraformrc: At 3:16: illegal char
│
╵

As a result of the above problems, Terraform may not behave as intended.
