Registration notification email are in the user language, not the organiser language

[dhrou]

Describe the bug
I have enable automatic email notification when a user register to my event. This email is in the user default language (german, polish...) instead of my (the organiser) default language (french, or at least english).

To Reproduce
Not easily as one would have to have dummy accounts set up with different language

Expected behavior
I would expect the email to be in my language (or the default language of the event is there is such thing)

Screenshots
Email I've recived:

(I got another one in polish, but the bulk of the emails are in english

Additional context
This is the event concerned

Indico event using indico v3.2.7

thanks, clearly a bug. and likely just in time before i'm releasing 3.2.8 ;) [edit: will more likely be fixed for 3.3 since it's not a simple one-liner as i thought]

"Organizer language" is not a thing in this context, because this notification is sent to a list of emails, not to specific users.

I think that would make sense here is to use the event's default language (if one has been set) or otherwise the instance's default language.

Similar bug: When you create a registration for someone else as an event organizer, that user receives the registration notification email in the organizer's current language.
