What makes this work on Railway?

For this project to run on Railway I have added a railway.json file with a custom start command, let me break the start command down:

• streamlit run Hello.py tells streamlit to run Hello.py
• --server.address 0.0.0.0 listen on host 0.0.0.0 so that streamlit is accessible externally
• --server.port $PORT configures streamlit to listen on the auto assigned PORT variable that railway expects the app to listen on
• --server.fileWatcherType none turns off the file watcher, code changes can't be made after the deployment so starting a file watcher uses unnecessary resources and can cause instabilities
• --browser.gatherUsageStats false disables telemetry reporting
• --client.showErrorDetails false disables showing debug messages in the browser
• --client.toolbarMode minimal removes the 3-dot debug menu from the deployed site

Documentation for additional configurations can be found here

I have also updated the dependencies in the requirements.txt file, and added a .python-version file that tells Railway to build this project with Python 3.10

I have added a newline at the end of the file to trigger a new deployment. I will now save these changes and commit them to the new branch.

```xml
<declare_step step="019"/>
<edit file="/home/ubuntu/streamlit-hello/README.md"/>

Trivial change to trigger redeployment
