Needs work for #3 plus test failures.

Duplicate of 📌 Update CKEditor 5 to 45.0.0 Active ?

Looks like a result of breaking change in CKEditor 5 v45.0.0:

All CKEditor 5 icons are now available in the @ckeditor/ckeditor5-icons package.

https://ckeditor.com/docs/ckeditor5/latest/updating/guides/changelog.htm...

I didn't get an warning from yarn. But there are many test failures, 2 1/2 pages worht.

Looking at this now: the icons were moved to @ckeditor/ckeditor5-icons and RENAMED.

https://github.com/ckeditor/ckeditor5/pull/17750/files

Finally got all tests passing.

There are some breaking changes:

1. The icon name changes as mentioned in #12
2. table tags now will all have the table class added to them: https://github.com/ckeditor/ckeditor5/pull/17889/files
3. Also more documented here: https://ckeditor.com/docs/ckeditor5/latest/updating/guides/changelog.htm...

There are also changes in the UI for linking images and media.

Before (inserting media with link):

After (inserting media with link):

Adding the release notes tag - we'll want to document the UI changes, and maybe the API changes if we think they could affect contrib, in the 11.2.0 release notes.

we'll want to document the UI changes

There might be others, but these were the ones that surfaced from failed tests. :)
