Fixes #573 A padding is added for the headings of the Example section to give gap between heading and images

Hi! This will affect all h2s, probably breaking the layout in tutorials that include it. The tutorials page has a similar look and addresses it by adding the following tailwind class to their h2s: https://github.com/processing/p5.js-website/blob/753bb06aba1221c5a60cb6158fa806d66e8a71eb/src/layouts/TutorialsLayout.astro#L53

Maybe we can take the same approach here instead?

Thank you for the suggestion @davepagurek. I have removed the previous update and added the Tailwind class
