update deployment example on third party hosting service

[12rambau]

https://voila.readthedocs.io/en/stable/deploy.html#deployment-on-heroku describes how to deploy a voila application on Heroku. Since November 28th 2022, Heroku hobby plan (the free dyno and stuff) has been removed and existing deployment have ceased to run.

Is there another 3rd party free hosting service recomended by the team ? (appart from binder that is still working amazing)

I'm using render.com which works nicely (only tried solara so far, not yet voila).
A drop-in replacement for Heroku is https://railway.app/ which (after adding --Voila.ip=0.0.0.0 to the argument) managed to deploy
https://github.com/maartenbreddels/voila-demo
at https://web-production-5a28.up.railway.app/ without issues.

let me try the railway.app think, it looks nice. Note that I'm already facing an issue with the environment (as a GIS developer I always need GDAL and GDAL is not nice at all)

worked like a charm: https://map-app.up.railway.app

I'll keep this one open if I (or anyone else) find the time to update the documentation

I guess that's a memory issue? But yeah, apart from that it runs.

I have this one that still works while I investigate the map one: https://panel-app.up.railway.app
