chore(ci): MDBook Workflow

[refcell]

Description

Introduce a new book.yml github ci workflow based on reth's book.yaml.

This will require the specified https://stack.anton.systems url to point to a deployed github page.

Alternatively, there may be a way for a deployment service to automatically build and deploy the site on a trunk update. (ie when a pr is merged into main, some service automatically builds and deploys the mdbook to the specified https://stack.anton.systems site).
