Fix TestPyPI workflow: add --index-strategy unsafe-best-match (#601)

uv's default index strategy finds packages like pytest on TestPyPI
first (e.g. pytest v0.0.0.dev1), then tries to resolve all its
dependencies from TestPyPI too, which fails. Adding unsafe-best-match
lets uv pick the best version across all indexes.
