Add hook_requirements() warning for sites with JSON:API, error if assertions are enabled

Thanks for creating this, @danielveza! 🙏

Added the warning.

Almost ready! 👍

Thanks @wim leers, I've used the same logic in \Drupal\experience_builder\EventSubscriber\ApiMessageValidator::isProd() to check if assertions are enabled.

• Should we change this to a common function? (ApiMessageValidator::isProd()) is a private method
• Should the priority be changed to REQUIREMENT_ERROR if assertions are enabed?

#8:

• Possibly. Let's wait for there to be 3 occurrences, to avoid premature abstraction. For now, please add an @see to the other place.
• Yes 🙏

Thanks @wim leers. Committed the changed
