Rule proposal: no-action-on-submit-button

{{! bad }}
<button {{action "cancel"}}>cancel</button>

{{! good }}
<button type="button" {{action "cancel"}}>cancel</button>

because there should be a submit action on <form> instead, to catch any submit event. and if a <button> is not a submit button, there should be type="button"

@viniciussbs https://github.com/ember-template-lint/ember-template-lint/pull/950 implemented exactly that 😃

I think there is a tad more nuance here. As I don’t think that <button {{action 'foo'}}></button> itself is bad, it is only bad when contained within a <form>, right?
