Fix positional parameter ordering in validate-typescript-apphost.ps1

[Copilot]

Adding new optional parameters in the middle of a PowerShell param(...) block shifts the positional indices of all subsequent parameters, which is a silent breaking change for callers using positional binding.

Changes

• eng/testing/validate-typescript-apphost.ps1: Moved the three new optional parameters ($PackageProjectPath, $PackageName, $UseConfiguredPackages) to the end of the param(...) block, after $Secrets, preserving the original positional order of all pre-existing parameters.

Before (breaks positional callers):

param(
    [string]$AppHostPath,       # pos 1
    [string]$PackageProjectPath, # pos 2 — NEW, displaces existing params
    [string]$PackageName,        # pos 3 — NEW
    [switch]$UseConfiguredPackages, # pos 4 — NEW
    [string[]]$WaitForResources, # pos 5 — was 2
    ...
)

After (non-breaking):

param(
    [string]$AppHostPath,        # pos 1
    [string[]]$WaitForResources, # pos 2 — unchanged
    ...
    [string[]]$Secrets,          # pos 6 — unchanged
    [string]$PackageProjectPath, # pos 7 — NEW, appended
    [string]$PackageName,        # pos 8 — NEW
    [switch]$UseConfiguredPackages # pos 9 — NEW
)

This was the first time I tried fixing it in the github web interface with copilot (mainly just to get experience trying it this way.)

I prefer doing it the other way, but I believe this is fine to address the review comment left by the copilot code review on the original PR.

Pull request overview

This PR adjusts the PowerShell parameter list in the TypeScript AppHost validation harness to avoid silent breaking changes for callers that rely on positional parameter binding by appending newly introduced optional parameters to the end of the param(...) block.

Changes:

• Appends $PackageProjectPath, $PackageName, and $UseConfiguredPackages after the existing $Secrets parameter to preserve the original positional ordering of existing parameters.
• Updates the $Secrets declaration to include a trailing comma to allow additional parameters to follow.
