* Convert symbol hash keys to strings when calling .perform_async
Fixes a warning from Sidekiq 6.4.0+ about perform_async arguments
which are not equal when passed to perform (`JSON.parse(JSON.dump(arg))`
should equal arg).
This is a safety measure to prevent passing objects (like classes, or
model instances) rather than their representations (like a class name,
or a model's attributes hash).
This warning will be an error in sidekiq 7
* Turn warning into an error in non-production environments
* Use string keys for reaction notification and article fetched
Missed these two on the first pass
* Update example argument hashes for #enqueues_on_correct_queue
Since this calls perform_async under the hood we need to pass json
safe hashes in the test cases as well.
https://github.com/forem/forem/blob/main/spec/workers/shared_examples/enqueues_on_correct_queue.rb
* Convert keys from FollowData#to_h to string before perform_async
I'm not sure enough where else (outside of notification) to_h is being
called, so I'm converting here when building args, rather than in
FollowData#to_h, which might be my next step.
* Let FollowData#to_h return a hash with string keys
Update spec to use string keys as well.
* Make to_h return string keys for ReactionData
Like FollowData, the #to_h method is only used to call
notifications (this is used to enqueue sidekiq jobs).
* Remove a key that was in the hash
Since reaction_data calls to_h, it gets string and not symbol,
keys. Call Hash#except with a key that was actually there.
I saw the following error in Honeybadger:
```
[PROJECT_ROOT]/app/services/notifications/reactions/send.rb:61 :in `call`
old_json_data = notification.json_data
previous_siblings_size = notification.json_data["reaction"]["aggregated_siblings"].size if old_json_data
notification.json_data = json_data

```
As I was exploring the error, I saw that we were making assumptions
about the data coercion. These are valid and somewhat stable
assumptions, but I wanted to look a little deeper into the situation.
This refactor helps consistently negotiate two situations where we're
transforming request-cycle models into lightweight data structures. It
also begins to show a path towards a generalizable "macro" for this behavior.

* Rename positive_reactions_count to public_reactions_count
* Add positive reactions count back in so we can remove it
* Use public_category method for reactions
* Add positive_reactions_count in case any old caches rely on it
* Add positive_rxn_count to account for API endpoints
* Remove unused method
* One more spot...
* Add method back in because of caches
* Update specs to match new functionality
* Fix typo
* Remove unused methods
