**Describe the bug**
running
```fh_railway_deploy MY_APP_NAME``` as described in the documentation fails with an assertion error
```assert nm=='railwayapp', f'Unexpected railway version string: {nm}'```

**Minimal Reproducible Example**
follow the instructions at https://fastht.ml/docs/tutorials/by_example.html#railway to setup railway
run fh_railway_deploy MY_APP_NAME
you will get the error.

This is caused because running railway --version
returns railway 4.8.0
which is not the expected result of "railwayapp"

```python
No python code is necessary
```
