Well, far right is a spectrum, obviously. But a party that equates immigration of a particular religion as terrorism is not "mild immigration restrictions" in my reading.
I cross-checked Wikipedia's information with another source: https://www.connexionfrance.com/news/french-election-is-it-c...
I don't know about that party, but National Rally doesn't say that, and also polls around 34% of French people. So it remains that the Wikipedia "far right" definition is a very wide spectrum.
