Support to detect file links in output

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.67.0 (system setup)
• OS Version: Windows_NT x64 10.0.19044

Steps to Reproduce:

1. Open a workspace folder, say /home/juxeii/projects/myproject
2. Create an empyt file, say gtestLog_testfoo and save this under /home/juxeii/projects/myproject and under /home/juxeii
3. Create a simple vsc extension and write both file paths to an output channel like so:

const outputChannel = vscode.window.createOutputChannel('MyExt');
const testfileuriBad = vscode.Uri.file(path.join('/home/juxeii', 'gtestLog_testfoo'));
outputChannel.appendLine(testfileuriBad);
const testfileuriGood = vscode.Uri.file(path.join('/home/juxeii/projects/myproject, 'gtestLog_testfoo'));
outputChannel.appendLine(testfileuriGood);

On my extension it looks like this

[5/10/2022, 12:57:31] INFO: Log file: file:///home/juxeii/projects/myproject/gtestLog_testfoo
[5/10/2022, 12:57:31] INFO: Test file file:///home/juxeii/gtestLog_testfoo

The output channel provides two file link, both of which I can click. But only the first link file:///home/juxeii/projects/myproject/gtestLog_testfoo opens the file, while the second fails: This occurs both when working with remote ssh on wsl2 on windows, and with a remote linux machine. Is this intended behavior not letting open files outside the workspace?

The error log in the output window gives Log (Window)

EDIT: open the folder /home/juxeii as workspace root, and I can open the file again. This confirmes that somehow the workspace root is in play here, which has a problem with links in the output window to files outside the workspace.

Turning into a feature as this works as intended currently. We need to expand the output link detection to handle file links if we want to support this scenario.
