add keybinding for search-history (#9930)

# Description

This PR adds a keybinding in the rust code for `search-history` aka
reverse-search as `ctrl+q` so it does not overwrite `history-search`
with `ctrl+r` as it does now.

This PR supercedes #9862. Thanks to @SUPERCILEX for bringing this to our
attention.
