fix: gpt-4o.toml has inconsistent knowledge date format

[brunusansi]

Description

The file providers/github-copilot/models/gpt-4o.toml uses knowledge = "2023-09" (YYYY-MM format), but most other model files use YYYY-MM-DD format (e.g., knowledge = "2025-03-31" in claude-opus-4.6.toml).

Expected

Change knowledge = "2023-09" to knowledge = "2023-10-01" to match the YYYY-MM-DD convention used across the repo.

Note: GPT-4o's actual knowledge cutoff is October 2023, so the month should also be corrected from 09 to 10.
