fix(lib): doom-project-find-file: remove +vertico/consult-fd-or-find

When +vertico/find-file-in was replaced in 60e22fd with
+vertico/consult-fd-or-find, it changed a key behavior for
doom-project-find-file for Vertico users: instead of displaying an
initial list of all files under the target directory, it would display
nothing until the user entered in N * `consult-async-min-input`
characters, causing confusion (see linked comment).

Since Vertico integration modifies project-find-file-in's interface
appropriately, I leave it to that command instead.
