Integrate with tool version managers like Aqua and mise

[o-l-a-v]

Prerequisites

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

Summary

There are now multiple multiplatform tools that can manage PowerShell versions as any other dev tool, like:

• Aqua: https://aquaproj.github.io/
  • aqua-registry: https://github.com/aquaproj/aqua-registry/tree/main/pkgs/PowerShell/PowerShell
• mise: https://mise.jdx.dev/
  • Uses Aqua registry (and other sources)

It'd be cool of vscode-powershell somehow could integrate with external tools for easily setting what PowerShell version to run for a session. It doesn't have to be tool specific, but maybe instead of hardcoding a path to pwsh.exe one could do trigger a command:

• mise use pwsh@<version_supplied_by_vscode_powershell>; mise where pwsh@<version_supplied_by_vscode_powershell>

Which then tells what path to pwsh.exe vscode-powershell should use.

Proposed Design

I think this is two asks both of which are feasible:

1. Teach VS Code to search for PowerShell installations in the directories that mise, Aqua, etc. install them. An example would be

   vscode-powershell/src/platform.ts

   Line 340 in 0c5f2f8

   private findPSCoreDaily(): IPossiblePowerShellExe | undefined {

   and the most annoying part frankly would be adding the appropriate test coverage. I'm happy to accept a PR for this as long as it comes with citation of documentation as to why it's now looking where. When done correctly, it should make those installed versions available in the PowerShell session menu, and should name them accurately. No defaults should change. This would essentially allow the user to skip manually adding these installations to powershell.powerShellAdditionalExePaths. They could access these PowerShells just by running "Show Session Menu" (or clicking the PowerShell langauage status icon) and could set it as a default by its name.

2. Teach mise, Aqua, etc. to edit the current workspace's powershell.powerShellDefaultVersion setting to the name of the desired PowerShell as it shows in the additional PowerShells after (1) is completed when running e.g. mise use. This is out of scope of this project and would be something to work on with those developers.

Note that I'm saying this with no familiarity with these exact tools, and am assuming they operate somewhat like the Python and Ruby environment managers.
