fix(cli): remove bufler from excluded autoloads
fix(cli): remove bufler from excluded autoloads

I was discussing issues generating autoloads files from some packages
with someone on Discord, and they mentioned issues with
alphapapa/bufler.el, so I added doom-autoloads-excluded-files in
5d0f78106260, and also added bufler to it by default. In hindsight, that
doesn't make much sense as a default when Doom and its modules don't
even install bufler (and even if they did, this shouldn't be done in
core).
