Missing some Deft Mode Mappings

### What did you expect to happen?

After enabling `:ui deft` and entering Deft, either via `SPC n d` or `M-x deft RET`, Doom's keybindings should be in effect, as declared here:
https://github.com/doomemacs/doomemacs/blob/dd83c455bad0c77f6f903242dc7008b2f6bbe06a/modules/ui/deft/config.el#L22-L34

### What actually happened?

None of these keybindings are present upon entering Deft, or when viewing the Deft keybindings using `describe-variable` (in this case, `SPC h v` `deft-mode-map`)

Taken from `describe-variable`:
```
deft-mode-map is a variable defined in deft.el.

(Excluded the two buttons with weird unicode characters/keycodes at the bottom, bound to `deft-filter-increment`)

### Describe your attempts to resolve the issue

Copy-pasting the `deft-mode-map` from `modules/ui/deft/config.el` into my `$DOOMDIR/config.el` serves as a workaround that implements the keybindings correctly:

```elisp
(map! :map deft-mode-map
:n "gr" #'deft-refresh
:n "C-s" #'deft-filter
:i "C-n" #'deft-new-file
:i "C-m" #'deft-new-file-named
:i "C-d" #'deft-delete-file
:i "C-r" #'deft-rename-file
:n "r" #'deft-rename-file
:n "a" #'deft-new-file
:n "A" #'deft-new-file-named
:n "d" #'deft-delete-file
:n "D" #'deft-archive-file
:n "q" #'kill-current-buffer)
```

### Steps to reproduce

1. Open Deft
2. Press `escape` to enter normal mode
3. Press `q` to try to quit
4. Observe Deft having not closed

Can also attempt to use other keys such as `C-n` in insert mode, `a` in normal mode, etc.
