Add Pagination to the Challenge Listing Page

[dogukanteber]

We currently show all of the challenges that exist in our platform. Since the number of challenges is not much, that wasn't a problem, until now. We need to add a pagination to the challenge listing page as the number of challenges is increasing.

@dogukanteber @adrianmcphee ,

Given the current listings below, are we planning to paginate by 8 items?

[dogukanteber]

Well, 8 is not a round number but that's all we have in the current situation. We may shorten the width of each card and remove some of the left and right margins but I am not sure if doing that looks good.

Let's paginate by 8 items per page. We'll see how it goes and make necessary update when necessary.

@dogukanteber, Okay.

Can you assign this to me ?

[dogukanteber]

Sure!
