Add an Error pattern to help with required component props

This is [an idea](https://github.com/cloudfour/cloudfour.com-patterns/pull/1689#issuecomment-1080986815) @calebeby came up with as a way to help make sure required component props are not accidentally missed when using a given component.

> Maybe you could do something with [defined](https://twig.symfony.com/doc/3.x/tests/defined.html)? Maybe render a message instead of the component if a given prop is not defined? 🤔

> Oh yeah that might be helpful. IDK if it's worth it, but we could probably make a error pattern that is very visible/flashy and then go through all our patterns and make them render the error pattern if any of their required props are missing

It may not be a higher priority, but would be helpful throughout the implementation of the components.

Esamina il test Twig `defined` proposto e i pattern dei componenti esistenti per determinare come vengono identificate le props obbligatorie. Il lavoro è completato quando esiste un pattern Error ovvio e altamente visibile e i pattern interessati lo renderizzano quando mancano props obbligatorie; l’issue non indica file o test, quindi è necessario analizzare l’ambito dell’implementazione.
