Add a testcontainers_image field to the database config block. When set, sqlc automatically starts a local PostgreSQL Docker container, applies schema migrations, and uses it for analysis — then tears it down when done.

database:
      testcontainers_image: "postgres:18-alpine"

Does it have to be called testcontainers_image? Why not just image or container_image to not leak implementation details about the library used to the public API?
