Prerequisites

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

Summary

Context

• I use PowerShell across operating systems

• I customized additional PowerShell executables for vscode-powershell using powerShellAdditionalExePaths:

  "powershell.powerShellAdditionalExePaths": {
   "PowerShell 7.5 (macOS)": "/opt/homebrew/bin/pwsh",
   "PowerShell 7 (Windows)": "C:/<path>/<to>/pwsh.exe"
  },
  "powershell.powerShellDefaultVersion": "PowerShell 7 (Windows)",

• I'm syncing and reusing my vscode settings across operating systems

The problem

Every time I work with PowerShell files I have to bear the annoying warning of addtional executable I've configured for the other platform not being found.

Proposed Design

Introduce a new cross-platform/syncing firendly way to customize additional executables

Proposed interface:

type OS = "Windows" | "macOS" | "Linux"
interface AddtionalPowerShellLocation {
 name: String
 path: String
 os: OS
 default: Boolean | undefined
}
type Locations = AddtionalPowerShellLocation[]

To not break¹ existing powerShellAdditionalExePaths, it'd be a new additionalPowerShellLocations key for holding these locations:

"powershell.additionalPowerShellLocations": [
 {
 "name": "PowerShell 7",
 "path": "/opt/powershell/pwsh",
 "os": "macOS",
 "default": true
 },
 {
 "name": "PowerShell 7",
 "path": "C:/PowerShell/stable/pwsh.exe",
 "os": "Windows",
 "default": true
 },
 {
 "name": "PowerShell Nightly",
 "path": "C:/PowerShell/nightly/pwsh.exe",
 "os": "Windows"
 },
 {
 "name": "PowerShell Nightly",
 "path": "/opt/powershell-nightly/pwsh",
 "os": "macOS"
 },
 {
 "name": "PowerShell 7",
 "path": "/opt/powershell7/pwsh",
 "os": "Linux"
 }
]

Then vscode-powershell can filter out items that are not for the target platform, and launch the first additonal PowerShell executable it successfully resolved. Nothing changes for system fallbacks in this proposal.

powerShellAdditionalExePaths and powerShellDefaultVersion then could be marked as deprecated.

The proposed design might not be optimal, so please comment.
