Fix invalid framework GH workflow

Fix:
```
The workflow is not valid. .github/workflows/framework.yaml (Line: 8, Col: 1): 'env' is already defined
```

Also:
- consistently sort top-level `env` and `concurrency` (as in
  https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions )
- sort env variables alphabetically
