refactor: simplify sitemap scheduling process

- Removed conditional check for production environment in
  the initializer to ensure the sitemap refresh worker
  always runs at startup.
- Renamed Sidekiq configuration file from sidekiq.yml to
  sidekiq_scheduler.yml to better reflect its purpose.

These changes streamline the initialization process
for scheduled tasks and enhance the clarity of the
configuration files used in the project.
