Footer Links have no spacing between them

🐛 Bug Report

The links at the bottom of a docs page that link to the page prior and after have no padding/margin between them so if the browser is narrowed, they get pushed together making them hard to read.

To Reproduce

Make rather large names for the pages before and after and then shrink the browser until they collide.

Expected behavior

Just add a little margin so there isn't a complete collision that makes it hard to differentiate.

Example

"Introduction to Number" is one and "Finite, Countable and Uncountable Sets" is the next.

Run npx envinfo --system --binaries --npmPackages smooth-doc,gatsby,react,react-dom --markdown --clipboard

Ignored because the problem is just aesthetical and not technical
