Feature: Adding Ollama support

Screencast.from.2024-10-14.01.07.35.PM.webm

NOTE: I don't have an OpenAI account so I'm not able to verify the changes here didn't break OpenAI, someone with an OpenAI account should verify this still works as expected.

Description

• Adding support for Ollama by adding additional env variables
• Updated README to reflect changes
• Added sample envs for Ollama and OpenAI

QA

1. Copy .env-ollama.example to .env and update the OLLAMA_BASE_URL to point to your Ollama instance, making sure you keep the /v1 at the end and also set the model to a vision model you have pulled.
2. Run npm run dev, go to http://localhost:3000 and draw something
3. Click on Make Real and verify you get a result from Ollama
