Check compatibility with upcoming CKE5 v 45 in core

[indigoxela]

See the core issue: backdrop/backdrop-issues#6904

I can only see one problematic line:

openai/modules/openai_ckeditor/js/openai.js

Line 58 in 099185a

const dropdownView = CKEditor5.ui.createDropdown(locale);

The rest might be just fine. Didn't test anything, just looked at the code.

Suggestion (roughly and untested):

let dropdownView;
if (typeof CKEditor5.ui.createDropdown === 'function') {
  dropdownView = CKEditor5.ui.createDropdown(locale);
}
else {
  dropdownView = CKEditor5.createDropdown(locale);
}

To explain: By checking the current location, you're compatible with CKE5 v44 and CKE5 v45.

Yes, thank you @indigoxela that suggestion does make the editor appear, when it did not before.

Good news, with the latest additions to the core PR, no adaptions should be necessary in this module.

CKEditor5.ui.createDropdown will reliably exist (deprecated, but functional).
