Consider enabling which-key support for evil operators

[panchoh]

Hi!

I just discovered that which-key supports evil operators, (which I've tested successfully on my humble Emacs config).

This means that when in operator-pending mode, for certain operators that will consume either a movement command or a text object, which-key will show a pop-up with those that apply. I find this quite ergonomic, especially for learning and mastering the evil way™.

As explained in the docs, this support relies on two things:

• that which-key is loaded after evil, which will set which-key-allow-evil-operators automatically
• that which-key-show-operator-state-maps is (manually) set to t

I’d like to propose that this behavior be considered to be enabled in Doom Emacs, since I think it improves the overall experience.

(Note that this extra support is already enabled for god-mode, so having this would be consistent with that decission.)

Thoughts?
