feat: AboutSection component

[diogogmatos]

This component should serve as a "layout" for the sections of the /about page and should receive children inside so that we can "surround" anything we want with this layout. The layout of an AboutSection is composed of a title that can be vertical or horizontal depending on the view (desktop/mobile) and a subtitle that also changes position according to the view. It also has a "view more" button.
