Two pieces of animated entertainment, both aimed at children, both with pretty high viewerships, both featuring a scene in which a precious object is falling from the sky as a result of a villain attempting to claim it for themselves, both in which a husband and wife team realise that the only way to save the day is for the husband to throw the wife so she can catch it...
The issue is, everything you've said is still a coincidence. Yes, they're animated, and aimed at children and with a high viewership. But there is such a long list of things like that, it's hard to say that has anything is a reference, so you kind of have to take that off the table. That's like trying to point to a specific Star Wars reference in Lord of the Rings, with reason to back it both are popular film trilogies with a big fanbase and both big villains dress in head to toe armor.
Next up, a scene with a precious object falling from the sky, that happens a lot too. It's very common, especially with villains in multiple forms of media taking place in the sky. I can think of several Transformers episodes where this is the case. The other issue is it's kind of being to generalized with "villain". In one case a villain is actively present, in the other, he's more of a presence. One is a result of revenge for screwing up plans, the other is just kind of there. They're also two highly different types of villains.
So the last thing left is the husband and wife team. Plausible, except for the fact that again, they're too different. The setting is too different, the angle isn't right at all, they're thrown differently. It's just too different to be a reference, more like a coincidence that they both happen to end that way.
On top of that, that scene in Incredibles is hardly a memorable scene, or the highlight of the film. The part in Cutie Mark Chronicles with Rarity, could easily be argued as reference to the iconic scene in 2001 A Space Odyssey when the ape-men discover the Monolith. But this, if it were a reference, was a poorly done one. If it was, it took too long for anyone to notice. It wasn't clear enough.
That is why I believe it is just a coincidence. Or perhaps subconsciously a writer was thinking of the ending to Incredibles and was inspired by it. But I don't believe it was an intended reference.
