pixi add autocompletion

Problem description

Basically the same as mamba-org/mamba#3173 but for pixi :)

I assume you mean pixi add or pixi global install but this is much harder in Rust as we can't generate functions automatically for the shell auto-completion.

oh yes i meant pixi add

This is the biggest UX improvement we can do in my opinion but currently I see no way we could do this in a maintainable way without a library that can generate autocomplete scripts for multiple shells. And I don't think we should shift focus to build something like that ourselfs at this point in time.

There are a few conversations on clap and clap_complete, the combining issue: clap-rs/clap#1232

Closing this for now
