fix: correctly parse ps output on linux

[owl-from-hogvarts]

Fixes #1388

The issue was that ps's output was parsed by hardcoded indexes. The parsing function had been written three years ago. Obviously, ps output format has slightly changed. So I have written regex to parse it more in more flexible fashion. Tested on mine machine. Works grate

Notice, that checks for existence of shortName and fullCommand are not required. Whole regex does not match if any of these does not.

@owl-from-hogvarts thanks for your contribution. Since the processTree.ts implementation is originally copied from https://github.com/microsoft/vscode-node-debug/blob/main/src/node/extension/processTree.ts, I'm wondering if updating to the latest version from that source would slove your issue?

@testforstephen Latest version of original file works. But notice, that it uses deprecated str.substr method.

We can replace the deprecated substr with str.substring(...).

Seems meaningful. So, it is now up to you to do code review and choose implementation 😉

Hey! Who's willing to review this PR?) Two weeks have passed. This still need merge. Just a friendly reminder 😉

The file now uses original approach. Code readability enhanced
