README: “Open in Visual Studio Code” badge points to open.vscode.dev (DNS/NXDOMAIN)

[riyak145]

What’s wrong

Clicking the “Open in Visual Studio Code” badge in README goes to:
https://open.vscode.dev/microsoft/Web-Dev-For-Beginners
This fails with DNS/NXDOMAIN for many users.

Expected

It should open the repo in VS Code for the Web.

Proposed fix

Change the badge target to:
https://vscode.dev/github/microsoft/Web-Dev-For-Beginners

Repro steps

1. Open README
2. Click “Open in Visual Studio Code” badge
3. Observe DNS/NXDOMAIN error

Willing to contribute

Yes — I will submit a PR for this one-line change.
