[Article/Blog]: Spacing in between paragraph is off & missing style for unordered list

[proeung]

Problems/Motivation

• Currently, we have 16px spacing and the text paragraphs are too close (see - https://www.merative.com/blog/marcy-tatsch-curam).
• We don't have proper styling for the unordered list which was not part of the Blog Detail page Figma design specs.
