[Please Review] Automated Upgrade Of fastpages Template

[hamelsmu]

Summary of Changes

1. Moved various files under _fastpages_docs in order to make the repo more organized, there was too many files in the root.

2. Setup A Mechanism To Automatically Upgrade The Repository.

• An automated experience is only possible at the moment when users do not customize the styling and HTML of their site. When users customize HTML or CSS, there is no guarantee that a new version of fastpages will not collide with the customization.

Overview of Automated Steps

Things I would appreciate a review on

@jph00 @xnutsive

1. Does the flow make sense?
2. Please read the messaging in the PR, does that seem ok? You can find the language in this pr in the file _upgrade_pr.md
3. Please provide any other suggestions and feedback.

Some notes: This is far easier than trying to merge upstream changes into your template because:

• I am strategically copying only certain files, thus minimizing the chance for conflicts.
• If you do this yourself the commit histories are not related, so you have to jump through advanced git hoops yourself to make this work.
• As mentioned above, this only works well if users don't customize the styling and HTML of their pages.

Feedback is very appreciated.
