Add 3 links and update 2 links

[Paulojesus85]

What does this PR do?

Add 3 links to free courses on Youtube | Update 2 links because they are just the first part of the course. Thus, I just keep the two parts in tehe same layout.

For resources

Youtube - Curso em Vídeo

Description

Css - Part 1 and 2
HTML - Part 1 and 2
Database - MySQL

Why is this valuable (or not)?

Curso em Vídeo is one of the best plataform that helps new programers.

How do we know it's really free?

I did these courses. And they are on Youtube.

For book lists, is it a book? For course lists, is it a course? etc.

It's a course (HTML, CSS and Database)
