### Expected behavior

When I type `SPC-m` to see localleader keybindings in javascript, I should see [prefix text](https://github.com/doomemacs/doomemacs/blob/90b1b221fe7c20f2edef341a780e194cd22c7daa/modules/lang/javascript/config.el#L311) (like `npm`) for submenus.

### Current behavior

When I type `SPC-m` to see localleader keybindings in javascript, I only see `+prefix` for submenus. Here is the screenshot:



### Steps to reproduce

1. From a fresh doom install
2. Enable `javascript` lang in `init.el`
3. Open a `.js` / `.ts` / `.tsx` file
4. Type `SPC-m` and wait see the menu to open
5. You should see `+prefix` keybinding values
