[FAQ] Create main FAQ page

[ryangchung]

While the course registration page has been built by @MathyouMB (can be seen at https://ccss.carleton.ca/faq/course-registration/), we have decided to have a "main" FAQ page which encompasses all FAQ pages and allows for curated FAQs to be displayed on the main screen and have buttons leading to the FAQ page for each topic.

Most of the code can be repurposed from the reference commit below, and turn the layout for the two curated FAQ posts into a partial component to be reused.

Note: The borders should not be there, this is a rough sketch of the layout, with a header which has content which is TBD. The positioning of the buttons should not be exact, but instead be in the area that it is shown (eg.: top left or bottom right of the partial).
