Add Kent's youtube video to README

[farskid]

Thanks for creating this fantastic library!

A question:

@kentcdodds just did a very good video on why you shouldn't be using shallow rendering. I found it very helpful in order to know the problems with shallow rendering. It also convinced my to user react-testing-library which before that, was not that clear for me.

Can we put that video on top part of the readme? I think it will help other people to have a overview of why this library helps them and what are the pitfalls of their current shallow rendering tests.

Video URL: https://www.youtube.com/watch?v=LHUdxkThTM0

Also a suggestion:

Can we also have this sentence in the repo description please? it makes it even more clear. at least for me it was helpful.
This library is a replacement for enzyme!

@farskid : Good point regarding video link, but not sure about the line "This library is a replacement for enzyme!".

Can you raise a PR for the same? We would be happy to accept it. 👍

I'd say is an alternative to enzyme, that also does not preclude using it alongside enzyme in the same project (though hopefully not both in the same tests at the same time!) Could seem crazy, but it's a valid path for those that want to migrate from enzyme to react-testing-library, and can only afford to do it gradually.

[antsmartian]

@gnapse Well, I guess we no need to add any references to other libraries at all. We just say react-test-library allows you to write tests in better fashion in our docs and its user choice to pick it up or not.

@antoaravinth @gnapse Thanks for replying.
I'd send a quick PR to add the video link.
About the enzyme sentence, I picked it up from the readme! It's already there. so if you think it's not precisely true, I'd guess we should change it there too?

[kentcdodds]

It is true and we should call it out more. Perhaps it could be:

> Note: react-testing-library is a complete replacement for enzyme (though you can use them in one codebase to migrate over time).

Something like that anyway...

If we could make the YouTube link be one which has the devtips playlist that would be helpful: https://www.youtube.com/watch?v=LHUdxkThTM0&list=PLV5CVI1eNcJgCrPH_e6d57KRUTiDZgs0u
