how to maintain the translations up to date.

[yabellini]

We need to add:

• a new chapter or
• a section of the Translation and Review Guidelines.

I would prefer a new chapter titled "Maintenance Guidelines " or something similar. We can use @maelle's blog post on the topic as the starting point for the chapter.

I have already added a reference to this process in this version of the guide. But we need to expand on the content.
