Just a reminder that this can't merge until a) the feature is released and then also b) the English is released!! (or the page will have the wrong "translated" status.

Astro Release > English docs merged > translated docs can merge

Got it, will keep that in mind.

Some typo/nit, otherwise LGTM. Thanks!

Thanks for the quick updates!, @MoustaphaDev! Maybe I should leave the Requested change status until the English version is published to avoid an accidental merge? Otherwise, happy to approve now!
