Convert other html pages to Markdown

[adamvoss]

I was bored the other day so converted the rest of the HTML pages to Markdown. Unlike #84 where I wanted header anchors, there is no reason for these changes other than the format conversion.

Only changes I observed:

• The Markdown rendering uses smart quotes. Most noticeable is the apostrophe is rendered ’ instead of '. This could be configured if there is a desire to not have smart quotes.

• on example2, there is non-semantic vertical whitespace (a gap) after

  "The full entry schema
  The resulting schema is quite large:"

  but before the code sample in the current version. I did not preserve that gap because I couldn't see any reason for it (the other sections do not have that amount of gap)

Pandoc again deserves most of the credit. The commits have also been pushed to may master branch which can be viewed at https://vossad01.github.io/json-schema-org.github.io/

I was thinking about asking if you wanted to do this, but hey you've done it anyway! =D
Again, I'll probably need to wait to review this properly =]

Super thanks!

This says the file is unmodified but there are actually two small changes. Was that intentional?

[adamvoss]

Shoot, I didn't realize I opened this file PR against my master branch. I meant it to be my markdownify branch. That change should not even be here.

[adamvoss]

I see how that comment does not make sense. The comment means to say it is unmodified relative to the minima theme (the two modifications you see are reverting local change, that were instead moved into main.scss

@handrews I can't change what branch this is open against. Instead of closing and opening a new PR, I just pushed my markdownify branch to my master. I fixed this wording issue in my bundle branch, which is for PR #86.

@vossad01 thanks! @Relequestual or I will follow up.

I've got training for the rest of this week. Hopefull I can review this change after that! I want to make sure this PR doesn't change any content by visual inspection.
