Add a pagination to the page.

[donymvarkey]

As of now, pokeAPI restricts the size of data that gets when we fire the https://pokeapi.co/api/v2/pokemon/. This URL now include a offset and limit params(https://pokeapi.co/api/v2/pokemon?offset=0&limit=20). So only the first 20(according the URL) pokemon shows up. We can change the limit to whatever limit we want. But that is not well optimized. There is a huge amount of data. So can you update the project by adding pagination?
