[Feature Request] [listbox/select-rich] type-ahead selection

[tlouisse]

When we implement this, along with the key combinations multiselect, I think we got all wai-aria listbox specs implemented (probably for the select-rich as well) 👍

Specs

Type-ahead is recommended for all listboxes, especially those with more than seven options:
Type a character: focus moves to the next item with a name that starts with the typed character.
Type multiple characters in rapid succession: focus moves to the next item with a name that starts with the string of characters typed.
