fix setup instructions (#4615)

Browse Source 
## Problem

1. The local endpoints provision 2 ports (postgres and HTTP) which means
the migration_check endpoint has a different port than what the setup
implies
2. psycopg2-binary 2.9.3 has a deprecated poetry config and doesn't
install.

## Summary of changes

Update psycopg2-binary and update the endpoint ports in the readme
