Create [blocks] shortcode

[bobbingwide]

Requirement

Create a [blocks] shortcode that can be used to display the original content of the post.

The purpose being to be able to see the raw content on the front end, without any reliance on the JavaScript code.

The shortcode should provide some value add. Such as providing a summary of the blocks in the page.
Again, it's mostly educational.

Optionally, create a blocks block that does the same thing.
