Use a single template per-email and localise it within the template

[ericlinagora]

Currently e-mail templates exist in versions for en and fr. This ticket is about making a single template, and from within it calling translation labels (already available in the backend though rarely used).

Hi, I would like to work on this issue.

[ericlinagora]

Sure, welcome

Hi. I'm pretty sure I know how to deal with this issue, but I ran into a problem. I can't find a way how to test it. Do you perhaps have any ideas?

Hi, if this value https://github.com/linagora/twake-drive/blob/main/tdrive/backend/node/config/default.json#L114 is true, it should print emails in the logs. Heads up though, we're probably going to work on this soon too

I got the value set as true, but I can't find the logs anywhere. I thought that those e-mails generate when user grants access to files in his drive to another user and I was trying to replicate it, but I couldn't figure it out, so I think I'm misunderstanding something. Could you please specify when are those e-mails generated and where can I find the logs of them being sent?
Thank you.

It seems we had a few bugs in the debug e-mail output, I fixed them in this commit fdccfa5 . Sorry about that.

Are those logs supposed to be stdout, because I still can't see or find them anywhere.
