Remove waitForPromises in attachment_spec file
What does this MR do?
The spec/frontend/content_editor/extensions/attachment_spec.js spec is flaky. A potential source of flakiness is waitForPromises because it may happen before the Tiptap Editor object flushes all transactions that mutate the document.
This MR replaces waitForPromises with a utility that asserts the state of the document after N number of transactions. We identify that a transaction is applied after the update or transaction event is emitted. The utility returns a promise that resolves after the N transaction is applied.
