Gem and package need to be in sync.

Unfortunately the testing framework doesn't support the latest version of StimulusReflex.
This is a third party framework that doesn't seem to be maintained. Maybe we should convert these to ActionCable tests.

It contains a fix for stimulus_reflex 3.5.0-rc4, but hasn't been released yet.
podia/stimulus_reflex_testing#21

Now the user reflex spec works, but the products spec needs another fix. But we plan to remove it soon anyway.

There wasn't a simple path to upgrade them separately. I think it's fine to do both at once.

I ran stimulus_reflex:install. It skipped over most things, but did add gem redis-session-store without explanation. It's mentioned in the [documentation](https://docs.stimulusreflex.com/hello-world/setup.html#session-storage), but I don't think it's relevant to us so I removed it again.

Sigh.
