Note that oddly enough, on prod none of it is in French, and seems to have a later version installed, than what we have

Oh the reason for two installations is because we turned off auto-update, note that we had auto-update off initially, I did say ok to this, but didn't look too deep into it hoping that the version update would just fix it, but alas it did not it seems, i will try a few options.

• Keeping out auto-update, but updating the languagepacks.json --> This, in tandem with also updating the install version pin seemed to fix it
• bringing back in the auto-update --> unnecessary, but unsure what will happen in the future if it will break it.

Got it to work like this, need to make some changes and will push /test further
