Note we're absolutely positioning the link instead of the icon; that way
keyboard users will be able to focus on the icon. Until now, users would
focus on an empty link.
For the same reason, we couldn't use `click_link` with Capybara, since
it would fail to click an empty link. Now we can.

Setting the color to `$white` or `#fff` while setting the background to
`$brand` is a pattern we were using in many places. Since we're going to
edit it in order to fix the `::selection` behavior, we're defining the
pattern in one place.
Using the name instead of using the name and the price is IMHO more
consistent with the rest of the application, particularly for screen
reader users. Writing texts clicking those links is also easier.
I think the main reason why we used the price as part of the link was so
the clickable area was bigger. We can accomplish the same result with
CSS.
Using flex we don't have to rely on JavaScript to equalize the item.
Besides, we've had problems with JavaScript in the past.
We're also adjusting the width of the elements; previously, even though
we defined a width of 16.666% for each element, only five elements would
be on the same row. It happenend because these elements were styled with
inline-block and the generated HTML contained a newline character
between <li> tags, meaning a space character was introduced between
elements. The width of the mentioned space character wasn't being taken
into account when calculating the width.
Using flex, there's no space character between items and we have to
define the margin between them. We're taking this margin into account
when calculating the width.
