URL "https://rebuildinglaravel.com" is wrong.

The URLs "https://rebuildinglaravel.com/" in [_posts/03-03-01-how-it-works.md](https://github.com/laraveltherightway/laraveltherightway.github.io/blob/master/_posts/03-03-01-how-it-works.md) at line 8 and line 9 are wrong. It seems like the URL is changed to "http://rebuildinglaravel.com/" (uses http instead of https).
