Read the article you posted. It doesn't say France is selling Sudan weapons.
It says "Amnesty International representatives call on France and its European partners to press for an effective international arms embargo to be imposed on Sudan" and that "France and its European partners should urgently pressure states concerned by these sales, and international bodies, to impose an effective international arms embargo on Sudan."
The article mentions who those states are. The UAE, Russia/Wagner, China, and Libya. It also mentions that a lot of the weapons are of Soviet and Iranian design. It does not mention France supplying Sudan weapons.
Also, how is France supposed to impose a weapons embargo without a military to monitor shipments? That was a rhetorical question. No need to answer.
Anyway, agree to disagree and all that. No point continuing this discussion.
