create implication summer_festival -> festival

A summer festival is a kind of festival.

I'm not sure about this, because these festival tags are pretty generic, and it's not uncommon for users to use them on posts depicting outfits commonly worn during those holidays. See for example summer_festival white_background simple_background.

But then again the main festival tag has the same issue: festival white_background simple_background
