Basic Pagination for the official Tutorial

Hi everybody,

as I see passing questions about pagination and almost every website will need one,
it would be lovely if somebody could spare a few moments and add the *pagination*
to the official news section Tutorial from the Docs.

That's all ^^

I am updating my entire site, localhost, from CI3 to CI4, in fact catalogs of my discs and movies and I'm stuck in pagination. I hope that with the completion of the whole project there will be examples of use and clearer documentation.It seems to me, I am not saying, that the objectives of the new version are not restricted to better performance, security, etc., but competition with this or that framework. I believe this always limits us to the ruler of the one we intend to "match" ourselves.
