windows pixi global install git not working

### Solution to issue cannot be found in the documentation.

- [x] I checked the documentation.

### Issue

`pixi global install git ` behaves different to a project installation

On windows I've seen that I can get git into a project and use it then from the terminal
e.g.
```
pixi init git
pixi shell
pixi add git
git -h
```

but when I try to install it global I cannot execute it

### Installed packages

```shell
not applicable
```

### Environment info

```shell
not applicable
```

Start by reproducing the documented project commands and the failing `pixi global install git` flow on Windows, since no repository files or tests are identified. Compare how project and global installations expose `git`; done means the globally installed command can be executed from the terminal.
