SaaS connection documentation

[conceptualshark]

Purpose

• As we roll out additional connectors, having a template and basic instructions on how to use them will become more important. Additionally, the "Guides" section in the docs site was growing, with enough SaaS documentation pages to warrant their own director.

Changes

• Call out implemented saas connectors on their own pages
• Provide a breakdown of available endpoints in the listed/available example configuration
• Restructure some of the docs pages to break out saas config/docs into their own section

Checklist

• Applicable documentation updated (guides, quickstart, postman collections, tutorial, fidesdemo, database diagram.
• If docs updated (select one):
  • documentation complete, or draft/outline provided (tag docs-team to complete/review on this branch)
• Good unit test/integration test coverage
• This PR contains a DB migration. If checked, the reviewer should confirm with the author that the down_revision correctly references the previous migration before merging
• The Run Unsafe PR Checks label has been applied, and checks have passed, if this PR touches any external services

Ticket

Fixes #450

I really like the way you linked out to the API docs and summarized the available actions in a single place. What are your thoughts on adding something like a Right to Update column? Each endpoint can have a read, update, or delete so it's important to make the distinction between update and delete.

[conceptualshark]

Is it the case that we use "Update" to satisfy a "Delete" - ie, updating information where it cannot be deleted? If that's the case I think I'd rather change "Right to Delete" to be inclusive of Update endpoints, otherwise just make this a simple read/update/delete breakdown (without promising it satisfies right to access or right to delete).

I like how each SaaS connector has it's own dedicated page with very relevant API links and action summaries. I fixed a few typos with the Stripe endpoint to avoid the back and forth, so all that's left is your thoughts on the "right to update" addition.

This is a good direction for SaaS connector documentation. Each connector integration is its own mini project so the more documentation we have the better!
