Script to download all branches of a repository into different folders

checkout.ps1

<#
.SYNOPSIS
This script checks out all branches of a Git repository into separate folders.

.DESCRIPTION
To run this script, follow these steps:
1. Open PowerShell as the current user.
2. Temporarily set the execution policy for the current session to Unrestricted by running:
   Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope Process
3. Run the script with the repository URL as a parameter:
   .\checkout_branches.ps1 -RepoUrl <repository-url>

.NOTES
Changing the execution policy to Unrestricted allows all scripts to run in the current session. This is less secure but necessary for running unsigned scripts downloaded from the internet.
