feat: picker zero selection

[scomea]

📖 Description

This change modifies Picker's behavior when the maximum number of selected items is 0. In that case selecting an item in the menu won't add a selected item but instead just updates the query string to match for a more combo-box like behavior but with Picker's "loading" and "no-suggestions" pop-ups.
