Subject: [PATCH] feat(Get-Stats.Cmd.ps1): add PowerShell script to retrieve
 git statistics

The PowerShell script `Get-Stats.Cmd.ps1` has been added to the `Core/Commands/Get-Stats` directory. This script retrieves git statistics using the `git log` command with the `--numstat` and `--pretty=format:` options. It parses the output to extract the number of additions, deletions, and the filename for each commit. The script then groups the statistics by filename and calculates the total additions and deletions for each file. Finally, it sorts the statistics in descending order based on the total additions and deletions and selects the top N results specified by the `$Top` parameter.
