fix: ollama migration documentation (#2248)

# Description


38de2e7440/docs/developers/contribution/llm/ollama.mdx (L20-L25)

Due to architectural changes in the file system, the ollama
documentation is out of date.



The sql files are now nested inside a `migrations` directory instead of
at the root of the supabase directory.

Fixed by adding `migrations` to the path 

```bash
mv supabase/migrations/local_20240107152745_ollama.sql supabase/migrations/20240107152745_ollama.sql
supabase db reset
```
