Feature: Add sessionName debug setting to allow different PS for temp console

[JustinGrote]

PR Summary

We want to encourage people to use PS7 for their extension terminal, but need to give them an easy way to test and debug PowerShell 5.1 tests.

This adds a setting to enable the selection of a different PowerShell executable for the temp terminal. It also adds a launch config sample for Windows PowerShell.

This has the added benefit of being able to temp console other PowerShell exes, such as a latest PowerShell build.

Pull Request Overview

This PR adds a new temporaryIntegratedConsoleExeName setting so users can pick a different PowerShell executable for temporary debug consoles (e.g., Windows PowerShell 5.1). It wires the new setting through the session manager, debug feature, package.json schema, and example launch configs.

• Exposed powershellExeName parameter in createDebugSessionProcess and updated selection logic
• Added WindowsPowerShell debug configuration and sample launch.json entry
• Updated package.json with schema for the new setting

• The defaultPowerShell variable is declared but never used. Removing this unused variable will clean up the code.

let defaultPowerShell: IPowerShellExeDetails | undefined;

• There are no tests covering the new powershellExeName path in createDebugSessionProcess. Consider adding unit or integration tests to verify that custom executables are correctly discovered and invoked.

My only thought is that we tried to move away from "integrated console" to "extension terminal" but I am unsure how much of that name change made it to this particular feature.

[JustinGrote]

I can probably fix that up, stay tuned.

[JustinGrote]

So I can either fix it in this PR or we commit this and I submit another PR to rename/alias createTemporaryIntegratedConsole to createTemporaryPowershellSession. Which would you prefer?

[JustinGrote]

Seeing as this was merged I will address it in separate PR.

Oh yeah I didn't see it was set to auto complete.
