PPS Article refactored

[vv-monsalve]

Hi @chrissimpkins, following what we discussed today, as well as taking one previous font including an Article as a referent, I've rearranged the entire About section to give a better structure doing the following:

• Add the "standard" (less editorial) description at the top of the article.
• Including an <hr> element to divide the before from the Article text
• Attempting to add a heading for the Article
• Rearrange the text to move the mention of the Emojis under a subsection dedicated to them
• Adding the list of the available emojis.
• Final round on spell check grammar and turn it into third person.

@RosaWagner I think #7006 (the PR that is updating the font) should be merged first so this Article update overrides the Article included there.

There will be some conflict so I gonna do some little tweaks to the first PR so I can merge this one after.

resolved already
