Revert / vi binding due to priority bug (#15111)

Manually added bindings take priority to the vi-mode state machine in
reedline thus this addition blocked the use of `f/`/`t/` etc.

Partial revert of #14908

Addresses #15096 with a temporary fix. The full solution of that should
resolve it on the reedline side so you can have both the search option
and the availability of `/` in normal mode bindings
