fix(projects): normalize item.text for correct Windows support (#2275)

## Description
`Snacks.picker.projects` would not show correctly projects on Windows.
`item.text` was something like
`C:\Users\my_user\AppData\Local\nvim-data\lazy\LazyVim\.git\`.

By normalizing `item.text` it shows correctly the projects.
