Detect drifts on i18n messages

[ab-smith]

Given that the default language for the app is English, each new development adds messages to messages/en.json
However, we lack alignment with other locales, which can be somewhat annoying.
One thing that we can do is to have a basic python script that compares the keys of each locale's json against the English one and generate a list of the missing keys as they are on the english one so that we can pass it for a human for translation or a genAI chat without breaking the token limit.

Hello

I drafted something like this : #2536

Do you know if you plan to launch the script in the CI/CD, or manually whenever you want to send it to a bot/human ?
