LemonBreezes 1bc5f441f0 tweak: helpful-set-variable-function: use setq! ...

helpful-set-variable-function defaults to setopt if it's available, setq
otherwise. `setopt` is superior for this use case because it uses
custom.el's mechanism for setting variables (thus respecting custom.el's
setters and type checks), however, it is unavailable in Emacs 28 and
earlier (`setopt` was introduced in 29).

Doom defines `setq!`, which is a drop-in replacement for setopt, and is
functional in Emacs 28, so it is the better option here.
