Change default config file from solid_queue.yml to just queue.yml

Following Solid Cache's change in
rails/solid_cache#222.

As we aren't still in version 1.0, fine to do this as a breaking change
for now.

-This version changes how recurring tasks are configured. Before, they would be defined as part of the _dispatcher_ configuration.

Check the _Recurring tasks_ section in the `README` to learn how to configure them in detail.

+This version has two breaking changes regarding configuration:

 *IMPORTANT*: This version collapsed all migrations into a single `db/queue_schema.rb`, that will use a separate `queue` database. If you're upgrading from a version < 0.6.0, you need to upgrade to 0.6.0 first, ensure all migrations are up-to-date, and then upgrade further.
