[Feature] Unified Support for Ollama-Downloaded Models in GPT4All

[AleksNeStu]

Feature Request
Request to enable GPT4All to support models downloaded via Ollama (https://ollama.com/), which uses a different directory and structure compared to native GPT4All models, such as Ollama from Facebook.

Proposed Solution:
Add compatibility for loading models stored in Ollama's structure within GPT4All.
Provide minimal documentation to clarify how users can point GPT4All to Ollama's model directory.

Benefits:
Unifies model management across ecosystems.
Simplifies workflow for users utilizing both Ollama and GPT4All models.
