Thanks for the review.
It's not as easy as I thought.
I think we will have to restart from scratch.

If the selected text representing the quotation is a full paragraph, we will keep using the <blockquote> tag, else that <blockquote> tag should be replaced by a <p> tag and the inline quotation should be wrapped in a <q> tag.

Since ckeditor5.blockquote is coming from https://github.com/ckeditor/ckeditor5 there's no reason to open an issue on Drupal core side.
Either we can ask for that change on CKEditor5 side or improve and use CKEditor 5 Inline Quote → module (even if I think that this should be a core feature).

Therefore I am closing this issue.
