openResources won't work in Linux without sudo privileges.

[kurmasz]

Describe the bug

When I take my project that works on my Mac, and with all three GitHub Actions (linux, Mac, Windows), then try to run it on a Linux desktop, the openResources command fails silently. (No folder opens.)

After digging in, it appears that the call to open in codeUtil.js is failing because either:

• chrome-sandbox has not had setuid root, or
• open is not passing the --no-sandbox flag.

When I modified codeUtil.js to add the flag, the tests ran as expected.
I was unable to verify that setuid would fix the issue, because I don't have root privileges on the system.

Steps to reproduce

* Write a test that uses `openResource` to open a folder. (Assert that the folder appears in explorer).
* Run the test on Linux where `vscode-extension-tester` has simply been installed with `npm install`.  (No special action taken on `chrome-sandbox`.)

Logs

There are no logs, tests just fail.

Could be known limitation for Ubuntu we are facing from Ubuntu 24 - https://github.com/redhat-developer/vscode-extension-tester/blob/main/KNOWN_ISSUES.md#openresources-not-working-with-apparmor-2404

have you tried to use step for your GH actions Ubuntu pipeline, something like:

- name: ⚙️ Allow unprivileged user namespace (ubuntu)
   if: ${{ startsWith(matrix.os, 'ubuntu') }}
    run: sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

[kurmasz]

I am able to get it to work in Linux environments where I have root/sudo. In the environment where I can't use sudo, I have to use the modified codeUtil.js.
