Fix dev onboarding installation instructions

[LoTerence]

Overview

As a new developer joining the team, I should be able to set up a development environment on my computer without much trouble.

When assisting Roja set up the development environment on her local machine, I came across some issues that should ideally be resolved to make it easier for future devs to start coding.

Issues:

• Installation instructions documentation is outdated
• Its annoying to fork the repo for core team. It causes obstacles for efficient collaboration
• docker compose up doesn't work out of box. We need to use the docker-compose.dev.yml file which can be confusing and unclear for new developers joining the project.
• building frontend static files blocks the vite development server from being served by django for some reason. This was not caused by using git checkout with the main branch.
• docker compose up --watch flag didnt work at first

Steps should simply be:

1. make a dev.env file
2. run docker compose up --watch

I'd like for it to be as easy as possible for new devs to get started working on the project.

Action Items

• merge docker-compose.dev.yml with the original docker-compose.yml file
• There should be one docker compose up command that works
• Investigate frontend build issue. Make sure django always serves the vite development server, even if there are static build files

After the above is done:

• Update the dev installation instructions documentation
  • Include instructions to download the latest version of docker
  • (Maybe) include instructions to just branch from the hackforla repo instead of making your own fork if you are on the core team. Open source contributors should still fork
• Add documentation about the two different branches: main and develop and how they work.
• Update dev onboarding issue template with new documentation (ISSUE_TEMPLATE/dev_onboarding.md). (Warning: at the momemnt, this file is only in the main branch. It is not in the development branch)
