Before sending image suggestions notifications for our three partner wikis, we want to make sure they're translated to those languages (ru, pt, id).

Here’s where to direct people to translate things:
pt: https://translatewiki.net/w/i.php?title=Special:Translate&group=ext-imagesuggestions&language=pt&filter=%21translated&action=translate
id: https://translatewiki.net/w/i.php?title=Special:Translate&group=ext-imagesuggestions&language=id&filter=%21translated&action=translate

Acceptance Criteria:

• pt translations exist and are synced
• ru translations exist and are synced
• id translations exist and are synced

Note: We also need translations for the preference to opt in/out of the notifications, but that's covered in T292146
