Fix Docker image build command

[risu729]

Summary

• fix the Dockerfile to invoke the scraper with valid Cargo CLI syntax
• pass the required --year latest-with-data argument to scrape_n_batch_insert
• keep the image build aligned with the current CLI contract so the build can reach the GHCR push step

Verification

• cargo run -- scrape_n_batch_insert --help

Context

The failing Actions job was exiting during docker build on RUN cargo r -- scrape_n_batch_insert -release. That command passed -release to the application instead of Cargo and omitted the required --year argument, so the image build failed before any GHCR push could happen.
