🩹 [Patch]: Encode all PowerShell files using UTF8 with BOM (#8)

## Description

This pull request makes a minor change to the `scripts/main.ps1` file.
The change appears to be the addition of a Unicode Byte Order Mark (BOM)
at the beginning of the file, which can help with encoding recognition
in some editors and environments.
