Cross platform open file

[CarlAndersson]

I'm migrating to using pixi tasks to run various python-related scripts. Most of these generate some output that the user typically wants to open in the default application on their desktop. It would be convenient to have a built-in cross-platform command in the task shell to open files in the desktop.

On macos, this is done with open path/to/file.txt, and spaces can be handled with quoting open "path/to/file with space.txt"
On windows (powershell), .\path\to\file.txt seems to work, and spaces should be quoted like .\"path\to\file with space.txt"
I don't have access to any non-apple unix platform at the moment, but a quick google indicates xdg-open as the equivalent to macos open.
