Confirm search and stash binding

Since i've updated, i couldn't manage to either rebind the keys for confirming a search or naming a stash, wich were previously dictated by `keybinding.universal.confirm`. I believe that this is due to the changes introduced in #4860.

My relevant config:
```yml
keybinding:
universal:
confirm:
goInto:
submitEditorText:
confirmMenu:
confirmSuggestion:
confirmInEditor:

```
