css update title wrap + links in footer

[lindsayplatt]

Still noticed some tiny details in how-to-gdp that would be useful for future vizzies.

On mobile, the header words wrapped and disappeared:

This fixes that:

Desktop remains the same:

Also in the footer, the title "Related Visualizations" looked and acted like a link but didn't link to anything, so changed the template. Same for the title of the related vizzie, but I added the URL to that since it should link.

No noticeable appearance, but underlines on hover only work for the ones with links now.

@mwernimont could you take a look and merge when ready? it's short.

I would make the title smaller on mobile over making room for it to wrap.

Simple font-size change when it goes to Desktop to make it bigger, as it will look better if no wrapping occurs

Resized font based on screen size.

Mobile:

@mwernimont did I do that right?

I like that more than wrapping!
