feat(#25): custom databases (#33)

* updated database to be an env * removed git modules add DBT_POSTGRES_HOST * initial script setup * began writing script for generating configuration files * completed building scripts waiting on adding tests * fixed script generation bug * removed unused variable * structuring docker bootstrap * removed all docker settings * fixed the docker startup bug in bootstrapper * about to pull in bug fix * production readygit add .git add . * fixed ci build bug * removed makefile because it's useless * added default database and version listing * updated documentation to give instructions on adding databases * added typescript to the dependencies * removed the wrong tsc compiler * escaped characters in .env * fixed dbt transformation issue * added postgres table to env templates * removed postgres table * added postgres table for dbt * added comments * Update README.md Co-authored-by: Lore <lorerod@gmail.com> * Update README.md Co-authored-by: Lore <lorerod@gmail.com> * Update env.template Co-authored-by: Lore <lorerod@gmail.com> * Update README.md Co-authored-by: Lore <lorerod@gmail.com> --------- Co-authored-by: Lore <lorerod@gmail.com>

 ### Prerequisites
 
 - `Docker`
-- `Make`
 
 ### Local Setup
 
 The local environment setup involves starting Logstash, PostgreSQL, PostgREST, DBT, and CouchDB. This configuration facilitates data synchronization, transformation, and storage for local development and testing. Fake data is generated for CouchDB. The required environment variables can be found in the `env.template` file, which should be customized accordingly for the specific deployment needs.
