fix: install Windows executable when executing install.sh in Git Bash

[jdblischak]

Closes #965

This PR downloads and installs pixi in a Git Bash shell on Windows. I've updated install.sh to properly download the Linux Windows executable. However, the command chmod +x "$BIN_DIR/pixi" doesn't work on Windows, so I can't run pixi after downloading it. Any ideas?

Hmm, when you are on Windows, you should download the Windows binary. Or do I misunderstand something?

[wolfv]

The chmod stuff can likely be skipped on Windows.

Doh. Good point. I was the one misunderstanding something. Now I understand how this can work. I'll test and push an update

Ok, now I've got it working in Git Bash

bash install/install.sh
## This script will automatically download and install Pixi (latest) for you.

Cool! Then we just need to fix pixi shell next :)

I also confirmed that my updates to support Git Bash did not break a standard installation in Ubuntu:

bash install/install.sh

CI is green. Ready for review. Please let me know if you'd like me to rebase onto main

Looks good, one small comment

Thank you @jdblischak and @wolfv, this is much appreciated.

I left a comment here that might offer a solution to the pixi shell issue, via the pixi shell-hook --shell bash method: #417 (comment)
