without-browser-env-var is not specified, so tools like create-react-app attempts to start a browser at the vscode defined path and crashes

Sorry for the incomplete data, I will try to edit the issue with the logs and paths appended later

OS/Web Information

• Web Browser: Any (Chrome)
• Local OS: Mac OSX
• Remote OS: Ubuntu
• Remote Architecture: amd64
• code-server --version: 4.0.1

Steps to Reproduce

1. Run npm start on integrated terminal for code-server
2. Crashes immediately trying to look at browser.sh from vscode

Expected

npm start should start, not crash.

Actual

Crashes

Notes

This is the line that gets appended to the browser env so react crashes (as there should not be a browser env file) https://github.com/microsoft/vscode/blob/6249dab4fe849d0ad11500fabd28ddc204ef12da/src/vs/server/extensionHostConnection.ts#L60

code-server version 3.12.0 doesn't crash

This issue can be reproduced in VS Code: No
