[Story] Baseline documentation for MPS

[Gnuxie]

Description

As a protection developer I should have access to documentation for how to develop protections with the matrix-protection-suite. This documentation should probably attempt to follow the dvio documentation system unless anyone can inform us of an alternative.

Acceptance Criteria

• There is reference documentation for all of MPS. This is partially complete with typedoc support.
• Contributing guidelines exist for MPS itself and github actions exist to run unit tests and typedoc.
• Conceptual documentation exists to explain policy rooms, policy lists, revisions, protections, capabilities and protected rooms sets.
• A how to guide exists for scanning timeline events
• A how to guide exists for scanning new members
• A tutorial exists for creating a new protection that does something simple, it doesn't have to protect the room, it could equally be a welcome of FAQ bot.
