Pixi install reports access denied in CI jobs

[j-rivero]

Some jobs have been failing with:

C:\Windows\Temp\pixi\project>call "C:\Windows\TEMP\pixi\pixi.exe" install  
  × failed to link libzlib-1.2.13-h2466b09_6.conda
  ├─▶ failed to link 'zlib.dll'
  ├─▶ unexpected io operation while removing clobbered file
  ╰─▶ Access is denied. (os error 5)

If we check in powershell what is locking the directory:

PS C:\Users\Administrator> Get-Process | Where-Object { $_.Modules.FileName -match "C:\\Windows\\Temp\\pixi\\project" }

This makes sense since gz-transport is linked to zlib. We need to find a way of cleaning up these processes.

Until we implement a zombie killer, these processes needs to be killed manually inside the node or the AWS node needs to be killed so a new is spawned.
