[Doc] Update GitHub organization name to patterns-ai-core (#968)

The repository URL has changed from https://github.com/andreibondarev/langchainrb to
https://github.com/patterns-ai-core/langchabinrb.
This update helps avoid unnecessary redirects from the old URL to the new one.

The same applies to https://github.com/patterns-ai-core/langchabinrb_rails.
Since there is no new chart for "Star History" under patterns-ai-core/langchabinrb,
the existing one remains unchanged.
