fix(pwsh): Use global:error[0] for most recent error in powershell (#3584)

Browse Source 
* Use global:error[0] for most recent error

The current version use $error[0], which is for the module instead of the global status and is always $null, so the $lastExitCodeForPrompot is always $origLastExitCode (see https://github.com/starship/starship/issues/3485 for a related bug).
It should be replaced with $global:error[0] 
Comments are also updated
