[docs] Fix dead link to live demo

[oliviertassinari]

To reproduce the bug, go to https://mui.com/toolpad/examples/npm-stats/#check-out-the-live-app.

I used the opportunity to fix the redirection.

I landed here checking that I wouldn't break anything by deleting the example repo that is on Render, now that it moved to Railway:

https://dashboard.render.com/usage/inv-cm932juv3ddc7381bgi0/view

Deleted.

Are there any objections to deleting the rest? It doesn't seem that we need:

https://dashboard.render.com/

I looked a bit at moving completely out of Render.com, I have tried to move the MUI Toolpad apps to Railway, https://github.com/mui/mui-public/blob/master/tools-public/railway.toml, https://mui-publictools-public-production.up.railway.app. It looks ok, but there seems to be one main problem: https://docs.railway.app/guides/environments#how-come-my-github-pr-wont-deploy.

Railway will not deploy a PR branch from a user who is not in your team or invited to your project without their associated GitHub account.

It forces to add all the team members, so Render is likely still cheaper.

Looking at our current memory usage:

(this is for tools-public)

Can we scale these back to the starter plan? Or is the startup peak still blocking us? It would mean at least 3 apps going from 25$/month to 7$/month (tools-private, tools-public, npm-stats). Add to that the removal of toolpad,toolpad-demo services (2 times 15$/month) and removal of a service of a PR that seems to have gotten stuck (25$/month) that could reduce the overall bill with 109$/month

Yeah, with the memory usage improvements the $7/month instance should work!

@Janpot It sounds like we can do this 👍

👍

the removal of toolpad,toolpad-demo services

I have worked on this. We still had a few apps depending on https://master--toolpad.mui.com, they are now all migrated. I have downgraded these two to the free plan. I would still like to see them, find it helpful to envision how things could look like.

Alright, it looks like the January bill is going to be a lot more sized to our needs. Thanks!
