[2.0.0-beta2] Component validator wording

I have started a table to follow the changes (still empty, but let's work on it the next days): https://docs.google.com/spreadsheets/d/1uLGS_knoJ5dQ96lh2pmEUnthzok28K1l...

Also, add an annotation in the messages which are addressed to component authors targeting UI Patterns instead of low-level SDC. For example, "You should declare a story in the definition"

And perhaps whether it's a Twig thing vs SDC thing, e.g.

starshot_demo:button Error The exact same as just testing the Twig 75 {% if attributes is not empty %}{{- attributes|raw -}}{% endif %}

Twig level :wink:: "is not empty" is useless except when Twig is configured in a very specific way, whcih is not the case in Drupal

Not to do with wording but it would be nice to be able to just get Schema warnings/errors or just Twig and to be able to "turn off" some things (e.g. Notices).

Also, should the "Unknown variable: is_dismissable" in the Twig maybe show up as a notice in the schema list? Not sure but perhaps easier if people are focused on fixing the schema vs the twig.

Thanks for your feedbacks. We will work on this in second half of August.

Awesome 👏
