Resources | Add resources to learn

[Phosphorus-M]

We need a better list of resources to learn Rust.
With the preference in Spanish because the website is in Spanish but all the resources with some reputation are welcome.

I suggest:

• The book
• Rustlings
• Rust by Example
• Learning Rust
• Some playlist? Our videos maybe?
• Our own beginner's guide or repository?

We can add more, I'm waiting for suggestions.
Maybe more articles for intermediates?
