Add support for autocomplete behind shim (like asdf)

[kedare]

Description

When using scw behind a version managed using shims like ASDF, the autocomplete doesn't work as it is generating the full path in the generated autocompletion code (even the scw shim is in PATH)

$ scw autocomplete script
autoload -U compinit && compinit
_/home/mpoussin/.asdf/installs/scaleway-cli/2.3.1/bin/scw () {
        output=($(/home/mpoussin/.asdf/installs/scaleway-cli/2.3.1/bin/scw autocomplete complete zsh -- ${CURRENT} ${words}))
        opts=('-S' ' ')
        if [[ $output == *= ]]; then
                opts=('-S' '')
        fi
        compadd "${opts[@]}" -- "${output[@]}"
}
compdef _/home/mpoussin/.asdf/installs/scaleway-cli/2.3.1/bin/scw /home/mpoussin/.asdf/installs/scaleway-cli/2.3.1/bin/scw

It would be interesting to have a --parameter to force the basename to scw (or configurable)

How this functionality would be exposed

A new parameter --basename for example to force a basename on the autocompletion generated code
