refactor!(vertico): remove multi-occur override

BREAKING CHANGE: remove override of multi-occur with consult-multi-occur

`consult-mulit-occur` is deprecated, and although it does have the
replacement `consult-line-multi`, I don't think that this override makes
much sense, as doom doesn't really touch `multi-occur` anywhere and this
would mostly be suprising to users that do use it.
