[Feature]: Show test steps in vscode extension test tree

[vitalets]

🚀 Feature Request

In vscode extension test tree show executed and failed steps after test run.

Example

I'd like to see the following structure in test explorer:

example.spec.ts
├─ Check title
   ├─ open Playwright site
   ├─ click "Get Started" link
   ├─ check title contains "Installation"

Motivation

Having test steps in test tree allows to instantly understand where error occurs and jump to the corresponding code line.

@vitalets Unfortunately, this is not possible today. VSCode test tree shows only tests, and does not have a notion of "steps". Also, steps are only available after you have run the test, and may change every time you re-run. I don't think VSCode is ready for this.
