update to cke v45 for v3

[i-just]

Description

Updated CKEditor to version 45.

Resolved breaking changes around the icon paths.

Switched from the 3rd-party Anchor plugin to the Bookmark CKE feature.

• The switch is necessary as the Anchor plugin was affected by the breaking changes around icon paths.
• If you have the anchor item in your CKEditor’s toolbar, it’s now rewritten to the bookmark item.
• Any anchors you have in the field’s content continue to work as before.
• The anchor plugin applied class="ck-anchor" to the anchors, but the bookmark feature doesn’t do that. The class will continue to be rendered in the front-end until the content is first saved after the update.
• The anchor plugin allows anchors to wrap text, and the bookmark converts it to an anchor tag without the text and places it before the previously wrapped text. (explanation: Bookmarks: part 1 ckeditor/ckeditor5#17063 => Scope > Functional requirements > 3rd bullet point)
