[BUG] VS Code extension not showing proper error when node cannot be found

[KrysKruk]

Context:

• Playwright Version: 1.29.2
• Operating System: Mac
• Node.js version: 14.6
• Visual Studio Code version: 1.74.3
• Playwright for VSCode extension version: 1.0.6
• Browser: -
• Extra: -

Describe the bug

VS Code extension shows warning Please install Playwright Test via running npm i --save-dev @playwright/test but when I go to "Output" -> "Window" I see an error:

[error] [Extension Host] Error: not found: node
	at ci (/Users/.../.vscode/extensions/ms-playwright.playwright-1.0.6/out/extension.js

I was struggling to run Playwright VS Code extension in my monorepo project. After installing node with homebrew it started working, so the error I posted was crucial here. It couldn't find node because I'm using nvm configured with fish so I guess it couldn't find an executable, but IMHO the most important thing here is to show users a proper error message.

Merging into #18954, you don't need to have a global node installation, it is a VS Code bug where it does not mirror the environment in time into the extension host.
