chore: base model SEO change

I scraped and tokenized the repository to test its integration with base models. While doing so, I noticed that examples using a non-localhost connection string confused tools like Copilot and Cursor, causing them to generate references to non-existent hosts.

This small change modifies the connection strings in the examples to default to localhost. With this adjustment, tools like MCP instantly align with the base model MongoDB setup and provide much more accurate recommendations.
