Feature Request: add 'Terminal' to $PSVersionTable to make support requests easier.

Summary of the new feature/enhancement

The powershell team will likely get an increase in bug reports from people running Windows Terminal, or want to see if some behavior is specific to Windows Terminal or the old terminal (which I guess is called ‘console’?). You might want to add the Terminal as a field to $PSVersionTable:

 $PSVersionTable

The PSReadLine bug report template provides the following script to help an issue author to collect environment data about whether you are running in Windows terminal:

    $hostName = $Host.Name
    if ($hostName -eq "ConsoleHost" -and (Get-Command Get-CimInstance -ErrorAction SilentlyContinue)) {
        $id = $PID
        $inWindowsTerminal = $false
        while ($true) {
            $p = Get-CimInstance -ClassName Win32_Process -Filter "ProcessId Like $id"
            if (!$p -or !$p.Name) { break }
            if ($p.Name -eq "WindowsTerminal.exe") { $inWindowsTerminal = $true; break }
            $id = $p.ParentProcessId
        }
        if ($inWindowsTerminal) { $hostName += " (Windows Terminal)" }
    }

   "HostName: $hostName"

@lzybkr @daxian-dbw Based on your PSReadline experience can you reword the request so that we could understand what useful would we add to $PSTableVersion about current terminal/console?
