fix(pwsh): Switched pwsh profile to use dollar hook for a more accurate success/failure handling (#1745)

Browse Source 
* [f]Use_global_dollar_hook_for_lastExitCodeForPrompt Switched to use the dollar hook, as source of truth for exit code of las command, included comments to clarify.

* fix: Adjusted accordingly to comments on PR.

* fix: Moved last exit code handling inside  if to reuse that variable.
