💥 add default init.el

Doom is moving away from supporting direct modification of its source
files, or private modules within Doom's source tree. Instead,
customizations should be relegated to ~/.doom.d/ (or ~/.config/doom/,
doom will respect XDG conventions if it sees this directory).

As suchm a default init.el is now supplied, which will break your custom
~/.emacs.d/init.el!

The quick fix:

  mkdir ~/.doom.d
  mv ~/.emacs.d/init.el ~/.doom.d/init.el

~/.doom.d/early-init.el is also available if you need to change crucial
settings before Doom loads anything. init.el will still be loaded before
any other module is.
