Breaking: #84055 - Migrate sys_notes away from extbase 

See forge#84055

Description 

To simplify the rendering of sys_note records and improve the performance, the usage of extbase has been removed from the extension sys_note.

Impact 

The model \TYPO3\CMS\SysNote\Domain\Model\SysNote has been removed, the repository \TYPO3\CMS\SysNote\Domain\Repository\SysNoteRepository now returns a plain result instead of objects.

It is not possible anymore more to change the template path of the extension.

Affected Installations 

Any installation which relies on the repository and model or changed the template by using TypoScript.

Migration 

To change the rendering of notes, override the hook and return a modified output.
