refactor: rename workers to jobs

- Change class names from Worker to Job for better alignment
  with Rails convention.
- Includes changes in BatchGenerateWeatherArtsJob,
  CleanAhoyDataJob, GenerateWeatherArtJob, and
  RefreshSitemapJob classes.

This refactoring improves the clarity and consistency of the
codebase by adhering to established naming conventions,
making it easier for new developers to understand the
role of these classes within the application.
