Alias commands to use GitHub Copilot CLI in PowerShell

# You should insert this script into your PowerShell Profile script so it exists in every session

# Fun fact: This script was mostly generated by ChatGPT by giving it the bash version of the output 
# from `github-copilot-cli alias -- "$0"` with a few fixes from me

Thank you, works fine 👍

Fantastic thanks!

When copilot cli needs to perform more than one action in powershell this gist fails:

PS C:\Users\danielp> ?? create a .txt file and inside the file write a haiku about sunsets

 ──────────────────── Command ────────────────────

New-Item -Path . -Name "haiku.txt" -ItemType "file"
Add-Content -Path "haiku.txt" -Value "The sun is setting"
Add-Content -Path "haiku.txt" -Value "The sky is turning orange"
Add-Content -Path "haiku.txt" -Value "The day is over"

 ────────────────── Explanation ──────────────────

○ New-Item is used to create a new item, e.g. a file.
  ◆ -Path . specifies that we want to create the file in the current directory.
  ◆ -Name "haiku.txt" specifies the name of the file.
  ◆ -ItemType "file" specifies that we want to create a file.
○ Add-Content is used to add content to a file.
  ◆ -Path "haiku.txt" specifies the file to add content to.
  ◆ -Value "..." specifies the content to add.

🕘  Hold on, executing commmand...
Invoke-Expression : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Command'.
Specified method is not supported.

To support multi line commands, add -Raw to Get-Concent.

I've updated the script with your suggestion @qqii, thank you!

@MattJeanes
Been trying to use Copilot CLI for almost a month now and I just came across this and it worked!
Thank you!

Thanks Matt, it's working fine 👍
