Propose standard and set up framework for technical documentation within the monorepo

[zenweasel]

From a suggestion from @aldeed, we are going to start building technical documentation within the monorepo including a local command that will launching a searchable "mini docs site" that is focused on developer documentation. Work should include initial research work, do getting the chosen framework working, creating a plan for documentation (structure, which pieces should be documented, etc) but does not include writing all the docs, which is work that should be distributed amongst the team.
