slsa.dev style: missing space between paragraphs

[MarkLodato]

The CSS on the slsa.dev website removes virtual whitespace between paragraphs, which makes it really hard to read. This is because (at least) there are two different rules that set p { margin: 0 }, one in main.css and one in tailwind.min.css. Adding a margin after the paragraph will fix it, though care must be taken to not break anything else. (I wish we had an easy visual diffing tool.)

If anyone wants to send out a PR to fix this, it would be most appreciated!

Tailwind also ruins <ol> tags by setting list-style: none. I think we need to get rid of tailwind and instead use proper css.

If we use add the markdown class (see #357 for example), it fixes most issues, but blockquote elements are formatted as horizontal boxes (flex model, different color, etc.). We'd need to fix that before applying that fix to the standards pages.
