!!! FEATURE: Upgrade CKEditor 5 from version 16.0.0 to 44.0.0 (#3883)

* FEATURE: try to update CKEditor (not yet working build)

* CKEditor Update: findLinkRange -> findSAttributeRange

OLD usage:
https://github.com/search?q=repo%3Ackeditor%2Fckeditor5-link%20findLinkRange&type=code

NEW usage:
https://github.com/ckeditor/ckeditor5/blob/master/packages/ckeditor5-link/src/linkcommand.ts#L166

* CKEditor Update: findAncestor

OLD impl: https://github.com/ckeditor/ckeditor5-table/blob/master/src/commands/utils.js#L20
OLD usage: https://github.com/ckeditor/ckeditor5-table/blob/c19bd145e9e8f2ce27e045c43e1247d25c877759/src/tableproperties/commands/tablepropertycommand.js#L41

* CKEditor: update highlighting plugin as well (basic editing seems to work)

* BUGFIX: Render table dropdowns with correct icons

The icons were broken and the fallback title was not aligned pretty well. So the SVG markup string will be transformed now to an data-uri and this can be used as image sorce.

* TASK: Hide type around buttons of CKEditor

The new type around buttons are not used by the neos ui at the moment and maybe we just dont need them. As the rendered SVGs without styled break the UI, we hide the buttons at the moment.

* TASK: Adjust E2E tests for creating new nodes

This is a workaround for the fact that the contenteditable element is not directly selectable for more information see https://testcafe.io/documentation/402688/reference/test-api/testcontroller/selecteditablecontent

* TASK: Adjust E2E tests to run testcafe with content editables

* TASK: Log the content tree state

* TASK: Write content via CKEditor instance

As the firefox could not deal with the testcafe workaround. We now write the content to the CKE

* TASK: Render CKE with headings

* BUGFIX: Try to fix content node creation

* TASK: Remove old placeholder patch

* FEATURE: Upgrade to CKEditor version 44.0.0

* TASK Remove console logs from tests

* TASK: Introduce cke-overwrite styles

Sometimes we need to overwrite global ck editor styles. We can put them here.

* BUGFIX: Fix space shifting when editing placeholders

* TASK: Hide aria-live-announcer thingy below neos ui
