add ollama as model provider

[warengonzaga]

It's time to add a new model provider that can run locally named "Ollama."

Here's the documentation: https://github.com/ollama/ollama/blob/main/docs/api.md

Goal:

• Create a script that can communicate with Ollama.
• Add that option to our existing options as another provider while leaving OpenAI as default. (for now)
• Add documentation on how to set up and use Ollama with Magic Commit.
• Ensure that we can support any model provided by Ollama.
