fix linting error in skyrl-cpu CI (ignore agent and examples) and change CI scope (#1143)

Changes the scope of CI running for the previously TX related tests
(`cpu_skyrl.yaml`, `gpu_skyrl.yaml`) to be:

```
- 'ci/**'
- 'skyrl/**'
- 'tests/**'
- 'pyproject.toml'
 ```

and changes the scope of previously train related tests (`cpu_skyrl_train.yaml`, `gpu_skyrl_train.yaml`, ...) to be more inclusive.
