docs: fix broken Accord Project VS Code extension links

[mi-vaishnavi]

I noticed that the links to the VS Code extension were pointing to the deprecated vscode-extension (returning a 404 error).

I have updated the links to the current Accord Project Extension in the following files:

started-resources.md

tutorial-vscode.md

tutorial-create.md

Hi @mttrbrts @dselman

I noticed that the VS Code extension links were pointing to the deprecated vscode-extension and returning 404s. This PR updates them to the current Accord Project Extension.

The changes are in:
– started-resources.md
– tutorial-vscode.md
– tutorial-create.md

I verified that the updated links resolve correctly. I’d appreciate your review and any feedback.

Thanks!
