Don't add autoload_paths to load_path

Quoting the Rails configuration guide [1]:

> applications running in :zeitwerk mode do not need require_dependency,
> so models, controllers, jobs, etc. do not need to be in $LOAD_PATH.
> Setting this to false saves Ruby from checking these directories when
> resolving require calls with relative paths, and saves Bootsnap work
> and RAM, since it does not need to build an index for them.

-# No longer add autoloaded paths into `$LOAD_PATH`. This means that you won't be able
-# to manually require files that are managed by the autoloader, which you shouldn't do anyway.
-#
-# This will reduce the size of the load path, making `require` faster if you don't use bootsnap, or reduce the size
-# of the bootsnap cache if you use it.

-# To set this configuration, add the following line to `config/application.rb` (NOT this file):
-#   config.add_autoload_paths_to_load_path = false

 # If you need to support Internet Explorer, add back `"X-Download-Options" => "noopen"`.
