tests: refresh talents-day baseline for repaired talent metadata
Follow-up to 89a745d9 and 647087bd.
The repaired frontmatter changes the metadata exposed by the sol talents-day endpoint for facet_newsletter and todos:daily, so tests/test_api_baselines.py::test_api_baseline[talents-day] needed a matching baseline refresh.
This file was not called out in the original baseline scope, but make ci showed it was a real downstream effect of the same fix. Kept unrelated sandbox drift out of the commit.
