feat: ability to use custom remote vscode URL

[wuiyang]

🆒 Your use case

I host my own Coder Code Server under domain vscode.xxxxxxxx, and open ports under domain portNumber.vscode.xxxxxxxx.

It would be great if I can use vscode feature in devtools with the VS Code Server that I have hosted in specific domain (vscode.xxxxxxxx).

🆕 The solution you'd like

Provide the ability to override custom vscode server URL (for the VS Code tab iframe URL) in vscode devtools config.

🔍 Alternatives you've considered

I can write my own custom tabs in nuxt.config.ts via hooks, but would love to see native solutions provided under devtools config.
