feat: pull in repos to allow for contract sharing

[codfish]

fairly sure truffle will pull in from node_modules by default. still need to do a lot of testing and decide what a long term approach is.

doing this to test right now docker build -t truffle:npm --build-arg GITHUB_TOKEN=$GITHUB_TOKEN . where $GITHUB_TOKEN is an env var holding an access token i generated. This is working but getting errors:

import 'organization-api/contracts/Organization.sol';
