Add "Open with Codeanywhere" badge to examples/studio/custom-datagrid…

[nkkko]

…-column/README.md

• I've read and followed the contributing guide on how to create great pull requests.
• I've updated the relevant documentation for any new or updated feature.
• I've linked relevant GitHub issue with "Closes #".
• I've added a visual demonstration in the form of a screenshot or video.

Why?

With Codeanywhere, devs and contributors can:

• Instantly launch a cloud or local IDE with remote dev environment.
• Automatically set up and configure a remote dev environments if a devcontainer.json file is present.

Benefits:

1. Faster onboarding for new contributors.
2. Consistent and ready-to-use development environments.
3. Flexibility to work in the cloud or locally.

🤔 this looks like it requires me to create an account with them. And are you sure this opens the example? It looks like it opens the whole Toolpad repo.

Hey, tough week so I rushed this. Will redo it if you think it makes sense?

• full example link
• cover all examples

There is a free tier and also in the latest version Continue.dev ai assistant.

Hi @nkkko we appreciate the interest, but it looks like it should have the same outcome as mui/material-ui#44499 (comment).

If we were to carry the overhead of a 3rd integration, I think we should consider those first:

• https://github.com/codespaces seems to have x6 more free use time, integrated with GitHub, doesn't ask for a phone number to create an account
• Replit. It has x10 more users https://docs.replit.com/replit-workspace/using-git-on-replit/running-github-repositories-replit#adding-a-run-on-replit-badge.

But even then, this class of dev environment seems to defeat the purpose, we are trying to have something that starts in a few seconds and without an account.

At the point where Toolpad needs a backend to run, maybe things will be different.
