This includes fixes for newer template lint rules that came along with
updating that dependency, which was necessary to be able to use
the no-curly-component-invocation rule. It also updates some curly
invocations that I missed in #8075.
This is part of #7834’s jQuery removal goal. It addresses a couple of jQuery-related deprecation warnings and also uses “native events mode” for ember-cli-page-object, which is needed so it doesn’t have to use jQuery via the Ember global.
