[TMP] - Pin dev version of Terraform container

Changed with:

```bash
find concourse/ -type f -exec sed -i sed -i '' 's/tag: 9cad30b5d5889a0b72173f39701d1620e24df82c/tag: terraform-aws-provider-upgrade/' {} +
```

Once the Docker image is built and tagged you can update this temporary commit with:

```bash
find concourse/ -type f -exec sed -i sed -i '' 's/tag: terraform-aws-provider-upgrade/tag: whatever-the-new-hash-is/' {} +
```

Commit message you can use:
