Blog publishing events are not handled correctly in Notifications RSS Feed

STEPS TO REPRODUCE

Preconditions: Blog Application is already installed.

1. Login with Admin
2. Create an user (e.g. U1)
3. Login with U1
4. Go to Notification Settings and set all Pages and Blog notifications to ON
5. Login with Admin
6. Create/update/comment a page (e.g. P1)
7. Create a blog post (published)
8. Login with U1
9. Click on Notifications bell > 'RSS Feed'

EXPECTED RESULTS

The RSS feed opens, showing properly the events performed by Admin (create/update/comment a page, publishing of a blog post).

ACTUAL RESULTS

The title of the event related to the publishing of the blog post is missing and the event's description is not translated (screenshot attached).

Also, if the blog post is published first (before the creation/updating/commenting a page), for all events (except the one related to blog), on 'Changes:' is displayed 'null' instead of the version (revision) link (which would lead to the diff).

However, if the page (P1) is created/updated/commented first, for all events, on 'Changes:' is displayed the same link leading to diff for the published blog post (no matter what the event is).

The issues could be reproduced also on XWiki 10.7 and could be related to XWIKI-15657.
