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"

No python code is necessary

Expected behavior
A clear and concise description of what you expected to happen.
