Support easily changing the endpoint of the openapi server

Great idea!

Just one issue, I don't really wanna give OpenAI access to my private documents.
Luckily there is an easy solution. Just allow changing the URL of the API endpoint.
This would enable easily using alternative back-ends like ollama that are API-compatible.
Probably just an environment variable would be enough.

I did some quick research and it looks as though you can set an environment variable for the baseURL (OPENAI_BASE_URL) since it's not explicitly passed. There's support for other params as well.

It looks like the URL is currently hardcoded:

documind/core/src/openAI.ts

Line 45 in 171766d

"https://api.openai.com/v1/chat/completions",

It would be really great if this can be set by an environment variable
