Update ember-raf-scheduler

[eliasdawson-addepar]

Update dependency ember-raf-scheduler and remove usage of registerWaiter method. registerWaiter is deprecated and a no-op as of ember-raf-scheduler@0.5.0. https://github.com/html-next/ember-raf-scheduler/blob/master/src/register-waiter.js.

Updating ember-raf-scheduler required additional changes. @html-next/vertical-collection@v4 depends on ember-raf-scheduler@0.3.0. The version conflict resulted in tests in the embroiderSafe scenario using 0.3.0 and thus not waiting properly. This PR updates @html-next/vertical-collection to v5 to prevent this conflict.

Updating @html-next/vertical-collection to v5 also required additional changes to the template and build config.

Unrelated to these changes, but StepSecurity failed the build because these were unpinned. @arshabh-agarwal not this is also blocking all Dependabot and other automated PRs. If we don't land this PR for some reason, we should pull this out to unblock.

Please check this carefully. I'm not very familiar with this format, and the {{#vertical-collection...}}...{{else} construction in particular.
