Usability Improvement: Warn when recurring task's schedule configuration missing

[apsoto]

This is user error, but I did spend a bunch of time troubleshooting why recurring tasks weren't being loaded.

I realized that my configuration was incorrect, but it wasn't clearly obvious until I ran through the configuration code and noticed that it skips loading the task if the schedule option is missing

https://github.com/rails/solid_queue/blob/main/lib/solid_queue/configuration.rb#L144

This could fail to load tasks for a number of reasons from user error:

• bad cut and paste (losing the schedule)
• spelling error on the option
• using incorrect option from another scheduling tool's config (cron: 0 * * * * )

Since we are loading from recurring.yml the intent is to have a recurring task. If the schedule option is missing, we should at least warn.

Thanks!

Ahh, indeed! So sorry about that. It was frustrating, and several folks brought it up 😅 🙈 . The good news is that we fixed it! We changed this behaviour in version 1.1.1, so if you update to the last version (currently 1.1.3), it'll fail loudly when a recurring task is invalid.
