Use grid layout instead of flexbox for infobox

[smallketchup82]

Currently we use a flexbox layout for infoboxes and manage rows and columns ourselves. This is honestly bad practice since we can let css do all of that for us.

We can use a grid layout instead. Define 2 columns and seperate every individual grid by the headers. Now, every property is aligned in rows of 2. If the total number of parameters is odd, one whole row is used by one property.

This should roughly match mediawiki and allow us to slam more information in the infobox, making it less tall, giving more room for the page's content.
