Incorrect German Translation in notifications

Issue Summary

When a user add a comment to a page, the notification for affected user is translated wrong

This issue appears on 6.15.9 as well as 7.3.3. There are translation issues with Notifications in German

Steps to Reproduce

The problem lies in two of the sentences display by the system when notifications are sent in Confluence.
"1 Kommentar zu dies Seite"
"testuserlb hat einen dies kommentiert"

Which would roughly translate back to:
"1 comment the this page" (not accurate)
"testuserlb has commented a this"(not accurate)

Expected Results

The correct translation would be:
"1 Kommentar zu dieser Seite" or "1 Kommentar auf dieser Seite"
"testuserlb hat folgendes kommentiert" or "tesuserlb hat folgenden Kommentar hinzugefügt"

Actual Results

The translations are seen as below.

"1 Kommentar zu dies Seite"
"testuserlb hat einen dies kommentiert"

which translates to

"1 comment the this page" (not accurate)
"testuserlb has commented a this"(not accurate)

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
