User Story: As an Author or Developer, I would like to use CKEditor5 as an engine for Richtext editor so that I can create, edit  the content in Magnolia both in Freemarker approach and headless

Context & Description:
The plan is to expose to the users 3 ways of CKEditor5 configurations to use with Rich Text Editor

• Magnolia Default configuration (example from CKE4 https://www.magnolia-cms.com/blog/customising-the-richtext-field-using-ckeditor.html?_gl=1*hryyje*_ga*NDUwNTExMjc1LjE2ODkxNzA3NjE.*_ga_61HQH88LT4*MTcwMjQ1ODU4My4xMDcuMS4xNzAyNDU4NTkxLjUyLjAuMA..#chapter-4)
• Extended Bundle with all features
• Customized

So we want to offer all plugins that we use to offer with CK4 on Magnolia default setup.

Expected result:

Expected result is to be able to edit in Magnolia App -  Magnolia set of plugins available from CK5 https://ckeditor.com/docs/ckeditor5/latest/installation/getting-started/predefined-builds.html#classic-editor

Acceptance Criteria:

• Im able to run the field through yaml definition
• im able to use all plugins presented in Magnolia editor and see result as formated text
