feat(util.mini): follow the user's mappings instead of hardcoded values (#4043)

Because I use the Colemak-DH keyboard layout, I have mapped 'i' to 'h'.
Therefore, the current mini.ai which_key prompts are inconsistent with
my keymap.


## Description

The names and prefixes used in mini.ai_whichkey() are hardcoded and
should follow the user's mappings.
