Composes markdown file representation of the docs site. Like astro does: https://docs.astro.build/en/guides/build-with-ai/#context-files

TODO

• review generation script to ensure no secrets could be leaked
• remove hardcoded site structure from generation script. It should automatically infer structure based on things already in place
