[openstreetmap-website] Diary cleanup (#218)

[Saman Bemel-Benrud]

This commit includes a few basic changes to make the User Diaries friendlier and easier to read. I adjusted the text styles and added a maximum width, to keep the line length under control

Here's a screenshot:

While working on the diary, I also modernized the markdown reference sheet with better markup and clearer styles:
