make windows feel more like zsh

A developer published a PowerShell configuration script that transforms Windows PowerShell into a Unix-like shell environment. The script replaces the default PSReadLine module, integrates Starship prompt and Zoxide directory jumper, and implements Unix-style commands such as 'la', 'll', 'which', 'touch', 'ln', 'alias', 'export', and 'ps'.
