Walkthrough's for PowerShell

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.

Summary

VS Code has a contribution point of Walkthroughs that appear in the Getting Started/Welcome view when the user opens vscode:

When you click on one, you get this:

I remember wanting to build this myself before this feature existed.

This would be a fantastic place to configure those polarizing options like:

• Choosing the version of PowerShell
• ISE Mode
• showing the terminal (powershell.integratedConsole.showOnStartup) I’d love this one!
• showing the command explorer

Proposed Design

Here are the docs on this: https://code.visualstudio.com/api/references/contribution-points#contributes.walkthroughs

Shouldn’t be too much work to add the contribution and some small code that actually changes these things (just commands).

Here’s a sample extension: https://github.com/microsoft/vscode-extension-samples/tree/main/getting-started-sample

Links to the documentation either on the vscode website or PowerShell Docs would also be great.
