Temporarily disable embark actions (and as a result, marginalia
annotations) for +vertico/find-file-in and functions that use it, since
because currently the embark actions don't inherit the intended
default-directory, embark actions might run unintentional destructive
operations if there are files with the same name in the
default-directory and the directory +vertico/find-file-in is run on.
