DRAFT:CDK - Add pp intro + components descriptions doc

[mitchpolygon]

Hello Anthony! Below you will find changes to the PP docs:

1. Can we make the "AggLayer-side components" a subheading to "Component descriptions"? They shouldn't be on the same level of hierarchy IMO because they are still considered a component description.
   1b. I believe there is a spelling error "Here are brief descriptions for each CDK FEP component" Should be "Here are brief descriptions for each CDK PP component."

2. Update the "See the high level view of the CDK PP chain architecture here" link under "AggLayer-side components" to go to the PP chain architecture diagram (currently goes to CDK FEP diagram).

Hi @mitchpolygon. Thanks for the suggestions.

1. The heading is now adjusted.

2. The link was intentionally and temporarily incorrect because these PRs are separate and their commits are not yet merged. Except for the Review Env of course, so I have corrected it in there.
   ... I will do the same on the actual PR only when finalising the docs for PROD.
