create implication super_mario_odyssey -> mario_(series)

Link to implication

Upcoming title for Switch.

We also really need to do something about the saturation of posts tagged with Super Mario Bros.

Right.
But when should this tag not be used...

topic #10735 had a plan for super_mario_bros. but I don't know if people actually enacted it. In practice, it's more umbrella than the actual umbrella tag mario_(series).

Anyway, I'll pass the implication for now.

The tag implication super_mario_odyssey -> mario_(series) has been approved.
