Add ai-search configuration to docs.yml

Summary

Added the ai-search configuration to fern/docs.yml to enable AI-powered search functionality for the documentation site. The configuration specifies that the search should index content from the docs directory.

Review & Testing Checklist for Human

• Run validation: Execute fern check or similar validation command to ensure the YAML syntax is correct and the ai-search configuration is valid according to the schema
• Test AI search functionality: Deploy or preview the docs site and verify that the AI search feature appears and works as expected
• Verify configuration placement: Confirm that placing ai-search after instances is the correct/recommended location in the docs.yml structure

Notes

• The configuration was added after the instances section and before title based on logical grouping of top-level configs
• No validation or testing was performed beyond verifying the YAML syntax appears correct
• This change enables the Ask Fern AI search feature for the documentation
